Abstract

Verstellventil für die Verstellung des Fördervolumens einer Verdrängerpumpe, umfassend
a) ein Ventilgehäuse (21),
b) einen in dem Ventilgehäuse (21) beweglich gelagerten Ventilkolben (22) mit einer Wirkfläche (23) für einen Ventilstelldruck (P20) eines Fluids,
c) eine Ventilfeder (25), die einer von dem Ventilsteildruck (P20) auf den Ventilkolben (22) ausgeübten Kraft entgegen wirkt,
d) und eine Verstelleinrichtung (27,28), mittels der der Ventilkolben (22) in Rich-tung der vom Ventilstelldruck (P20) ausgeübten Kraft oder gegen diese Kraft verstellbar istAdjustment valve for the adjustment of the delivery volume of a positive displacement pump, comprising
a) a valve housing (21),
b) a valve piston (22) movably mounted in the valve housing (21) with an effective surface (23) for a valve actuating pressure (P 20 ) of a fluid,
c) a valve spring (25) which counteracts a force exerted by the valve part pressure (P 20 ) on the valve piston (22),
d) and an adjusting device (27, 28), by means of which the valve piston (22) is adjustable in the direction of the force exerted by the valve actuating pressure (P 20 ) or against this force
