Axial piston pump to open hydraulic systems

摘要

The invention relates to the field gidromashinostroeniya, in particular axial piston pumps for the hydraulic systems of public and can be used in hydraulic machine tool, a mobile, road-building, and other mechanisms. Axial piston pump for open hydraulic system includes a main pump with suction and the pressure taps, the secondary pump sucking oil from the tank and generating a primary pilot pressure pump control mechanism. Summary of the utility model is that the axial piston pump to open hydraulic systems is formed on the basis of the axial piston pump for the closed hydraulic systems wherein flows the main and auxiliary pumps are separated together, for example, by installing plugs in the rear cover of the main pump in place of the auxiliary pump flow connection to the flow of the main pump for excluding the main charge pump. The achieved technical result consists in reducing the weight and cost of the inventive axial piston pump without deterioration of its performance.
