Abstract
A hydraulic motor apparatus includes a motor housing engaged to an end cap having a first porting system and an adapter connected to an external surface of the end cap and having a second porting system. A filter may be attached to the adapter and connected to the second porting system and a pressure reducing valve in the adapter is connected to the second porting system. The assembly may also include a controller operatively connected to the pressure reducing valve and system sensors measuring parameters affected by the output of the hydraulic motor apparatus, whereby the pressure reducing valve is operatively controlled by the controller in response to input from the system sensors.
Claims15
A hydraulic motor apparatus hydraulically connected to a hydraulic pump, the hydraulic motor apparatus comprising:
- a motor housing engaged to an end cap to form an internal sump, the end cap comprising a running surface connected to a first porting system formed in the end cap, an inlet port and an outlet port, wherein the inlet port and the outlet port are formed on a second surface generally perpendicular to the running surface;
- a rotatable cylinder block disposed on the running surface and located in the internal sump, whereby the rotatable cylinder block is hydraulically connected to the first porting system, and an output shaft providing an output of the hydraulic motor apparatus;
- an adapter removably connected to the second surface of the end cap and having a second porting system disposed therein, the second porting system being in fluid communication with the first porting system;
- a filter directly connected to the adapter and connected to the second porting system;
- and
- a pressure reducing valve disposed in the adapter and connected to the second porting system.
