Abstract

790,190. Rotary pumps and engines. RECHERCHES ETUDES PRODUCTION R.E.P. Aug. 17, 1956, No. 25292/56. Class 110 (2). An hydraulic system comprises an adjustable rotary pump A and a motor B both of the inclined-disc type. The inclination of a rotating disc 24, in the pump, is controlled by a lever 22, which is moved by means of a piston 43, Fig. 6, which is influenced by liquid under pressure controlled by pistons 44, 45. Each rotor has a central core 1, having a part-spherical surface which is truncated at the sides and maintained compressed between two pads 2, which are concentric with the shaft 3 to which they are fixed. Vanes 4 are carried by the core in slots and have relative movement with regard to the inclined, slotted rotary disc 24. Two flanged rings 5 prevent outward movement of the vanes and are held laterally by rings 6. Ball bearings 8 support the rotor shaft and take end thrust, and roller bearings 9 allow lateral play of the parts between bearings 8. Two steel rings 17, with hardened surfaces, are used to position shoulders 16 on either side of the stator. An annular space is provided around the periphery of the disc 24, this space being supplied with oil under pressure derived from the return flow from the pump. The disc 24 revolves between two low friction packing rings. The flow from the pump may be reversed by rocking the lever 22 over its dead-centre position, without altering the direction of rotation of the pumps. The connections between the pump and the motor include four wells 25, 26; 27, 28, arranged in pairs and carrying inlet and check valves 29, 30, soas to help eliminate air from the whole apparatus. An auxiliary pump 32, in the casing 14, is supplied with oil by a reservoir, and delivers it through a filter 33. Two piston valves 44, 45 are provided under the block holding a piston servomotor 43. Valve 44 controls the direction of propulsion, forward or backward and stopping of the apparatus, and valve 45 regulates the position of the servo piston 43, when running, the setting of the piston 43 being controlled by the lever 22. Oil, under pressure, is supplied on either side of the servomotor cylinder by way of inlets 48, enters annular grooves 49, and passages 51, 52 to the annular space between the two pistons 53, 54 of the valve 44, which is balanced, its central guide member having helicoidal grooves. As shown, the apparatus is stopped, an actuating lever 46, for the valve 44, being in the central position, Fig. 10 (not shown). Further passages 55 lead oil under pressure to the cylinder of the second valve 45. Braking of the motor is secured by progressive hydraulic blocking.
