Hydraulic pump
A hydraulic pump, in which two pump elements deliver from a common suction chamber and the delivery currents can alternately be jointly fed to a pressure outlet or can be split to two outlets of which one outlet leads back into the suction chamber, is to be simplified with regard to its construction...

| description | A hydraulic pump, in which two pump elements deliver from a common suction chamber and the delivery currents can alternately be jointly fed to a pressure outlet or can be split to two outlets of which one outlet leads back into the suction chamber, is to be simplified with regard to its construction.
For this purpose, the pressure-side chambers for the separate delivery currents can be connected via a one-way valve through which in the open state the delivery current of one pump element can be united with that of the second pump element.
The different delivery current guides are switched via control valves whose position depends solely on the pressure prevailing at the pressure outlet of the hydraulic pump.
The control valves to be switched are a joint component of a single control slide valve. |
