Abstract

1413249 Rotary positive-displacement fluidmachines DANFOSS A/S 26 April 1973 [26 April 1972] 19913/73 Heading F1F In a gerotor-type machine such as a pump or motor, a rotary annular valve-disc 29 to control the flow of fluid to and from the working spaces between the rotor 25 and stator 6 is supported by a bush 28 in a fixed annular valve-disc 8. A splined shaft 30 may couple the disc 29 to the rotor. A spring and pressure-loaded plate 34 may press the disc 29 against the disc 8. A ring of alternating oblong-circular openings 37, 38 may co-operate with a ring of similar passages 36 in the disc 8; and passages 39, 43 may communicate with inlet and outlet ports 1, 2 through annular chambers 42, 44. The discs 8, 29 may comprise annular elements 53, 54 and 58, 59 fixed to each other by pins 55, 60 and brazing. A splined shaft 22 may inter-connect the rotor and an input or output shaft 3. The teeth of the rotor may be rollers or vanes.
