42300762, Oct 28, 1980

Filed:

Sep 5, 1975

Appl. No.:

5/610719

Inventors:

Robert S. Mueller - Birmingham MI

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F02D 1306
F01L 118

US Classification:

123 9016

Abstract:

An improved valve disabler control for a multi-cylinder engine having individually pivoted rocker arms and an intake and exhaust valve pair for each cylinder. Half of the valve pairs are provided with valve disablers having rotatable sleeves. Rotation of the sleeves counterclockwise (ccw) allows sliding movement of the rocker arm fulcrums, thereby disabling the valves; clockwise (cw) rotation of the sleeves prevents sliding movement of the fulcrums, thereby enabling the valves. The improved control includes a link and a spring interconnecting the disabler sleeves for each valve pair. Each link rotates the intake valve disabler sleeve ccw in response to ccw rotation of the exhaust valve disabling sleeve. A slot connecting each link to the intake valve disabler sleeve allows cw rotation of the exhaust valve disabler sleeve before cw rotation of the intake valve disabler sleeve. Each spring provides a cw biasing force to the sleeves.

Inventors:

Robert S. Mueller - Birmingham MI

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F02D 1306

US Classification:

123198F

Abstract:

The actuator disclosed herein uses cyclic forces in a valve gear train of an internal combustion engine to selectively switch a pair of valve disablers between valve enabling and disabling positions. When the disablers are in the valve enabling position, rocker arm fulcrums are latched in a fixed position. When the disablers are in the disabling position, the rocker arm fulcrums are unlatched to allow sliding movement of the fulcrums. The actuator employs a spring which is preloaded to positions for switching the disablers between their enabling and disabling positions in response to movement of the rocker arms which are moved by cyclic forces from a camshaft.

US Classification:

136 89P

Abstract:

Providing printed circuitry in a sandwiched relation with a pair of flexible layers of non-conductive material, depositing solder pads on the printed circuitry and storing the resulting substrate on a drum, withdrawing the substrate from the drum and incrementally advancing it along a linear path, serially transporting solderless solar cells into engagement with the pads and thereafter heating the pads for thus attaching the cells to the circuitry, cleaning excess flux from the solar cells, encapsulating the cells in a protective coating and thereafter spirally winding the resulting array on a drum.

Appl. No.:

6/397739

Inventors:

Robert S. Mueller - Birmingham MI

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F16D 2504

US Classification:

192 329

Abstract:

A viscous coupling adapted to be positioned within the housing of a torque converter automatic transmission for use as a bypass of the torque converter and including an annular clutch lining secured to a side face of the outer peripheral portion of the coupling and a control valve assembly positioned in the outer peripheral portion to cushion the impact of engagement of the annular clutch lining with the confronting surface of the torque converter housing. The control valve assembly includes a rolling diaphragm which extends across the open end of an axially extending bore in the outer peripheral portion and is arranged to rollingly traverse the bore to successively cover or uncover a series of axially spaced leakage holes communicating with the main chamber of the torque converter and the bore. The end of the bore remote from the diaphragm communicates with the side of the coupling carrying the annular clutch lining at a location radially inwardly of the clutch lining so that, upon initial engagement of the coupling, leakage flow may occur through the leakage holes from the main chamber of the torque converter to the other side of the coupling to cushion the impact of the clutching engagement and the leakage flow is thereafter gradually cut off to apply the full clutch force as the rolling diaphragm traverses the bore to successively cover the leakage holes.

Assignee:

Eaton Corporation - Cleveland OH

International Classification:

F01L 134
F02D 1306

US Classification:

123 9016

Abstract:

An engine valve control mechanism for varying the amount of opening and/or timing of cylinder valve in a valve gear train of a multi-cylinder, internal combustion engine having an overhead camshaft which actuates the valve via a rocker arm pivotally bridged between the valve stem and a hydraulic lash adjuster. In one engine embodiment of the invention the valve gear train portion for each intake valve is provided with a valve control mechanism of the invention by providing a camshaft having a high lift lobe and two low lift lobes for actuating the valve and by providing a valve rocker arm including a rigid link defining a first cam follower for following the low lift lobes and a second cam follower pivotally connected to the rigid link for following the high lift lobe. A latch carried by the rigid link is operative in a first position to prevent pivotal movement of the second follower relative to the rigid link, whereby the valve is actuated by the high lift lobe, and operative in a second position to allow such pivotal movement, whereby the valve is actuated by the low lift lobes. In a second embodiment the low lift lobes are removed, whereby the valves are disabled when the latch is in the second position.

Abstract:

A torsional vibration damping mechanism (30) is disclosed in a clutch plate assembly (24) for a vehicle driveline. Mechanism (30) includes a set (36) of relative high rate helical compression springs 62, 64 for transmitting torque and alternating torsionals when a transmission input shaft (22) is connected to a load, a set (38) of relatively low rate helical compression springs (66) connected in series with spring set (36) and for attenuating torsionals when the shaft (22) is not connected to a load, and a viscous damper module (48) disposed in parallel with both spring sets (36, 38) and operative to dampen recoil of both spring sets. The viscous damper module is readily fitted to known clutch plate assemblies in lieu of mechanical friction dampers previously employed to dampen recoil of the helical compression springs in such assemblies.

International Classification:

F01P 702

US Classification:

Abstract:

A drive mechanism (26) momentarily reduces the speed of engine-driven accessories in response to vehicle acceleration or increased power demands to improve fuel economy and to provide additional horsepower for the vehicle. The drive mechanism includes an electromagnetic clutch (48) operative, when engaged, to drive the accessories at constant speeds relative to speeds of an engine (10) and a viscous coupling (60) operative, when first engaged, in response to disengagement of the clutch, to first drive the accessories at a minimum speed and then to increase the accessory speeds to minimize shift shocks when the clutch is reengaged. The coupling includes a housing (58) defining an annular compartment (108) containing an annular clutch member (92) and a viscous liquid. A working chamber (113) within the compartment, defined by confronting surfaces of the housing and clutch member, transmits torque from the housing to the clutch member via viscous shear in response to relative rotation therebetween. An annular reservoir (114) circumscribing the working chamber receives liquid from the working chamber and minimizes the amount of liquid in the chamber when clutch (48 ) is engaged.
