Dynamic pressure control for hydraulic pumps

摘要

The rotation speed dependent pressure controller has two conveyor wheels (3,4) and an oil pocket (18), extending adjacent to the conveyor wheel in a rotational direction for receiving conveyor oil. A conveyor quantity distributor device (5) has a control piston and an associated regulating spring for generating a controlling pressure. Both chambers of different pressure pistons stay above two stationary pipes in a pressure connection with the oil pocket. One pipe opens in the rotational direction of the conveyor wheel and shifted to another pipe in the oil pocket.
