  • Oscillating slide machine that pumps different fluid mediums at different pressures
    Patent number: 9394893
    Abstract: 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.
