Filed:

Sep 25, 1989

Appl. No.:

7/412211

Inventors:

Roy T. Burgess - Troy MI
Rajamouli Gunda - Rochester Hills MI

Assignee:

Vickers, Incorporated - Troy MI

International Classification:

F04B 126
F15B 1316

US Classification:

60222R

Abstract:

A rotary hydraulic machine which includes a housing having a shaft mounted for rotation within the housing about a shaft axis. A cylidner block is coupled to the shaft for co-rotation with the shaft within the housing and includes a plurality of cylinders disposed in a circumferential array parallel to and surrounding the shaft axis. A piston is disposed to reciprocate within each of the cylinders and is coupled to a yoke for determining displacement of the pistons within the cylinders. A valve plate is mounted on a valve block and includes kidney-shaped slots for registering with the cylinders as the cylinder block rotates, and thereby connecting the cylinders to pump input and output ports. A microprocessor-based controller is externally mounted on the pump valve block and includes internal memory having various remotely-selectable control programs prestored therein. Sensors responsive to pump operating conditions are connected to the pump control electronics, and include a first sensor responsive to yoke position, a pressure sensor responsive to pump output pressure and a speed sensor responsive to angular velocity of shaft rotation.

International Classification:

F01B 300
F01B 1304

US Classification:

92 122

Abstract:

A variable speed pressure energy translating device including a plurality of axially extending pistons and associated cylinders and a yoke engaged by the pistons and pivoted on a transverse axis for varying the displacement thereof, and a housing having spaced saddle bearing seats. The yoke has spaced complementary saddle bearing engaging portions and an arcuate bearing is seated in each of said seats. Each bearing comprises an arcuate body of polymeric material and an arcuate reinforcing member embedded in the body and having a plurality of perforations throughout which are fixed in the reinforcing member with the polymeric material extending through said perforations.

US Classification:

417222R

Abstract:

A bearing comprising a body of polymeric material and a reinforcing member embedded in the body and having a plurality of perforations throughout which are affixed in the reinforcing member. The polymeric material extends through the perforations. The bearing may have various configurations. The reinforcing member may comprise a thin metal sheet having perforations therein, a woven metal body defining the perforations, or adjacent woven metal bodies each having perforations. In one form, a backing member is adhered to on one side of said reinforcing member. Where a thin metal sheet is used, it has a roughened surface finish at the interface with the plastic body.
