Volume current variable displacement pump

摘要

Volume current variable displacement pump, comprising:a) a housing (1)b) a chamber, which in the housing (1) which is formed on a low pressure side of an inlet port (8) at a high pressure side and an outlet opening (9) for a fluid,c) a received in the chamber inner rotor (4), which is pivotable about an axis of rotation (d_I) is rotatable,d) a received in the chamber ring (3) with a central axis (d_A), the surrounding the inner rotor (4) and in the case of a rotary drive of at least one of the inner rotor (4) and the ring (3) with the inner rotor (4) forms at least one conveying cell, in which the fluid from the low-pressure side is conveyed to the high pressure side,e) and a on the housing (1) during an adjustment movement slip-free rolling adjusting member (13),characterized in thatf) of the inner rotor (4) on the adjusting member (13) about the axis of rotation (d_I) , is rotatably mounted andg) the position of the axis of rotation..
