US Patent:

40194256, Apr 26, 1977
Filed:

Feb 7, 1975
Appl. No.:

5/547905
Inventors:

Ralph Anthony Matzelle - Brimfield IL
Assignee:

Caterpillar Tractor Co. - Peoria IL
International Classification:

F01B 1304
US Classification:

91487
Abstract:

A hydraulic fluid pressure energy translating device comprising an axial multi-piston pump including an axially and laterally constrained barrel and a floatingly disposed port plate responsive to hydrostatic forces within the pump. The port plate includes hydrostatic pressure balancing means which tend to balance hydrostatic forces acting on the port plate during operation of the pump to maintain an optimum bearing clearance between the port plate and barrel, thereby controlling fluid leakage and maintaining adequate lubrication and support at this interface.

Appl. No.:

5/547907
Inventors:

Robert J. Huebner - Peoria IL
Carman P. Lynnes - Leonard ND
Ralph A. Matzelle - Brimfield IL
Richard L. M. Sears - Washington IL
Assignee:

Caterpillar Tractor Co. - Peoria IL
International Classification:

F01B 1304
US Classification:

91487
Abstract:

A hydraulic fluid pressure energy translating machine is provided with hydrostatic pressure-balancing means which communicate with the primary port to balance hydrostatic forces acting on the barrel during operation of the machine to maintain an optimum bearing clearance between the head and barrel, thereby controlling fluid leakage and maintaining adequate lubrication and support at this interface.
