Abstract
A pump for conveying a medium, in particular hydraulic oil, comprising a flow-control valve for controlling the flow of medium conveyed by the pump and a discharge channel (7) releasable by the flow-control valve. In order to prevent cavitation, a flow divider (17) is provided for dividing the discharge jet flowing into the discharge channel (7) and extends into the said discharge channel (7), and is spaced by a distance (a) from an orifice (9) of the discharge channel (7) facing the flow-control valve.
Claims19
A flow controller for controlling the flow of medium conveyed by a pump, the flow controller comprising:
- a housing having an axial direction, a valve bore extending in the housing along the axial direction;
- a discharge channel in the housing, the discharge channel having an orifice communicating with the valve bore to receive medium therefrom;
- a flow divider extending in the axial direction within the discharge channel and spaced from the valve bore and from the orifice, and positioned for dividing the discharge jet of medium flowing into the discharge channel from the valve bore through the orifice into separate flows following the flow divider, and including an incident flow projection positioned for receiving the jet from the orifice.
