Abstract

Die Erfindung betrifft eine Rotationspumpe mit regelbarem Fördervolumen, umfassend:
a) ein Gehäuse (3, 6),
b) eine in dem Gehäuse (3, 6) gebildete Förderkammer mit einem Einlass (4) für ein Fluid auf einer Niederdruckseite und einem Auslass (5) für das Fluid auf einer Hochdruckseite der Pumpe,
c) wenigstens einen in der Förderkammer um eine Drehachse (R2) drehbaren Förderrotor (2),
d) ein zu einer Stirnseite des Förderrotors (2) angeordnetes oder den Förderrotor umgeben des Stellglied (15), das für die Verstellung des Fördervolumens in dem Gehäuse (3, 6) hin und her bewegbar ist,
e) wobei das Stellglied (15) in Richtung seiner Bewegbarkeit mit einer von dem Bedarf eines mit dem Fluid zu versorgenden Verbrauchers abhängigen Stellkraft beaufschlagbar ist,
f) und eine in dem Gehäuse (3, 6) gebildete Laufbahn (3a), die das Stellglied (15) an einer Stellglied-Gleitfläche (15a) in einem Gleitkontakt führt,
g) wobei ein Gleitmaterial, das wenigstens eines aus Laufbahn (3a) und Stellglied- Gleit fläche (15a) bildet, aus wenigstens einem aus Kunststoff, Keramik, Nitrid, einer Nickel phosphorverbindung oder einem Gleitlack besteht oder von einer DLC-Beschichtung, einer Ferroprint-Beschichtung oder einer Nano-Beschichtung gebildet wird.

The invention relates to a rotary pump with adjustable delivery volume, comprising:
a) a housing (3, 6),
b) a delivery chamber formed in the housing (3, 6) with an inlet (4) for a fluid on a low-pressure side and an outlet (5) for the fluid on a high-pressure side of the pump,
c) at least one conveying rotor ( 2 ) rotatable in the delivery chamber about a rotation axis (R 2),
d) a to an end face of the conveyor rotor (2) arranged or surrounding the conveyor rotor of the actuator (15) which is movable for the adjustment of the delivery volume in the housing (3, 6) back and forth,
e) wherein the actuator (15) is acted upon in the direction of its mobility with a dependent on the need for a consumer to be supplied with the fluid actuating force,
f) and a raceway (3a) formed in the housing (3, 6), which guides the actuator (15) in sliding contact with an actuator sliding surface (15a),
g) wherein a sliding material, the at least one of career (3a) and actuator sliding surface (15a) forms, at least one of plastic, ceramic, nitride, a nickel phosphorus compound or a lubricating paint or by a DLC coating, a Ferroprint Coating or a nano-coating is formed.
