Abstract

The present invention is concerning a hydraulic pump system with integrated distributor valve, which is generally applied in a hydraulic circuit normally constituted of an oil deposit (39), a cylinder (40), a module of Pneumatic control (41), and a hydraulic pump with integrated distributor valve (42). The system object of the present invention presents a reduction of the accidents and ruptures in the gear box, operates with higher pressures, reduces the vibrations and prevents clearances and consuming of the pump. The present invention is applicable mainly to power take off's (43) that are located in the gear box of the trucks.
