Abstract
The invention relates to a pump comprising a pump unit, an intake line, and a valve device associated with same for implementing suction regulation of the pump, and comprising an intake region downstream from the valve device as viewed in the direction of flow of the medium conveyed by the pump.
Claims19
A pump comprising:
- a pump unit;
- an intake line;
- a valve device associated with the pump for implementing suction throttling of the pump;
- and
- an intake region downstream from the valve device as viewed in the direction of flow of a medium conveyed by the pump, the valve device including a switching valve having a solenoid for influencing a media flow passing from the intake line to the pump unit;
- the valve device having a closing element displaceable by the solenoid and moveable between an open position, at least one throttle position, and a closed position, the closing element including a sleeve having a cylindrical wall region displaceable in a direction parallel to a center axis of the intake line, the closing element having a cover that is provided with at least one opening, the cover further having a plurality of arms through which a coupling member is connected to the closing element, the coupling member connected to the solenoid, the at least one opening created by interspaces between the arms, and
- wherein the medium present in the intake line is able to penetrate into an interior of the closing element through the at least one opening.
