<p>The invention relates to a double hydrostatic pump, for high pressure. According to the invention, the hydrostatic pump has the medium pressure pump (9) with gear wheels, which supplies the oil into the high pressure inlet space through an aspiration channel (b) situated inside the body (1) of the pump, which communicates with a channel ( c) which is in connection with a needle inductor (10), as well as a channel (d) which is in connection with a one-way valve, which has a seat bushing (11), a ball (12) and a spring (13) supported on a guiding fluted tap (14), which communicates with some channels (e) which are in connection with some annular spaces (f), provided around the axial cylinders (15) of the high pressure pump, which supplies high pressure oil through some one-way valves, provided with some chairs (21), balls (22) and some springs (23), in a high pressure space (h), which is connected to a discharge nipple (24).</p> |
