Oscillating slide machine that pumps different fluid mediums at different pressures

摘要

A controllable hydraulic oscillating slide machine includes an inner rotor arranged in a housing and having cylindrical recesses. A bearing is formed in the housing, in which a co-rotating outer rotor is mounted eccentrically to the inner rotor, the outer rotor having several pivotably suspended slide drivers that engage into the recesses of the inner rotor for rotationally driving the outer rotor by way of the inner rotor and form modifiable chambers. The slide drivers may each be coupled to a piston that is guided in a respective associated recess. A pressure level different from that in the chambers between the inner and the outer rotor may be set in the chambers delimited by the recesses and the associated pistons so that two different pressure levels may be generated and two different consumers can be supplied using the oscillating slide machine.

1. A controllable hydraulic oscillating slide machine comprising:
an inner rotor arranged in a housing which comprises a plurality of cylindrical recesses; a bearing formed in the housing; an outer rotor positioned between the bearing and the inner rotor, the outer rotor is mounted and co-rotates eccentrically to the inner rotor, and the outer rotor comprises a plurality of pivotably suspended slide drivers, which engage into the plurality of recesses of the inner rotor for rotationally driving the outer rotor by way of the inner rotor; wherein each one of the plurality of slide drivers is pivotably attached to an associated piston of a plurality of pistons, and wherein each associated piston of the plurality of pistons is in turn guided in a respective one of the plurality of recesses of the inner rotor; a plurality of first working chambers delimited by the outer rotor, the inner rotor and the slide drivers, and the plurality of first working chambers are a plurality of modifiable chambers configured to modify a volume in a respective one of the modifiable chambers, such that the plurality of first working chambers deliver an exit flow of a first pressure medium at a first pressure level; a plurality of second working chambers fluidically separated from the plurality of first working chambers and delimited by the plurality of recesses and the plurality of pistons, such that the plurality of second working chambers deliver another exit flow of a second pressure medium at a second pressure level, and wherein the plurality of first working chambers and the plurality of second working chambers, respectively, are configured to at least one of (i) deliver the exit flows at the first pressure level and the second pressure level in which the second pressure level is a different pressure level from the first pressure level and (ii) pump the first pressure medium and the second pressure medium, the second pressure medium being a different level of pressure from the first pressure medium; wherein each associated piston of each slide driver of the plurality of slide drivers fluidically separates a first working chamber of the plurality of first working chambers from a second working chamber of the plurality of second working chambers.
