Filed:

Jan 4, 1996

Appl. No.:

8/582854

Inventors:

Daniel J. Lambert - Hubertus WI
Derek A. Dahlgren - Brown Deer WI
Thomas J. Stobbs - Brookfield WI

Assignee:

Applied Power Inc. - Butler WI

International Classification:

F16K 3106

US Classification:

251282

Abstract:

A bidirectional flow control valve has one port co-axial with a tubular spool and another port opening to the side of the spool, with openings formed in the sidewall of the spool to establish communication between the two ports. The end of the spool adjacent to the one port abuts the brim of a tubular hat-shaped insert which extends inside the lumen of the spool to a closed end on the distal side of the other port. Openings are formed in the sidewall of the insert which are in communication with openings in the sidewall of the spool via an annular groove in the exterior of the insert. The insert reacts against flow forces, helps equalize pressures from one end of the spool to the other, and does not increase the pressure drop across the valve.

International Classification:

F16K 3106

US Classification:

25112916

Abstract:

The magnetic interface between the housing and armature of a poppet type electromagnetically actuated fluid control valve creates a magnetic flux path through opposing axially and radially facing surfaces of the housing and armature to reduce the pull-in voltage of the valve at large axial gaps between the armature and housing.

Inventors:

Daniel James LAMBERT - Hubertus WI, US

International Classification:

US Classification:

Abstract:

A self charging electric vehicle includes a frame, at least one battery, a distribution box, an engine control unit, a plurality of drive axle systems, and a plurality of electric modules. The plurality of drive axle systems is positioned on the frame and a motor of each of the drive axle system is powered by the battery. A drive axle generator of each of the drive axle system re-charges the battery through the distribution box as the drive axle generator is selectively engaged with the motor by a clutch. The clutch is automatically operated by the engine control unit as the plurality of electric modules provides data back into the engine control unit so that the drive axle generator can be efficiently engaged with rotational motion of the motor.
