Abstract

1501695 Hydraulic reciprocating motors DBA 14 March 1975 [27 March 1974] 10674/75 Heading F1A A reciprocating piston hydraulic motor is disposed in a pressurized enclosure (not shown) and the cylinders (11 1 ), 11 2 , (11 3 ), 11 4 are connected in turn through pipes 12 to the enclosure and to exhaust, whereby the pistons 2 move to cause step by step movement of an output shaft 7. Each pipe 12 is connected to exhaust of enclosure pressure via a selector switch (not shown). At the end of each piston's inward stroke, the piston engages a respective limited stroke buffer piston 13, the flanged outer end surface 15 of the latter being subjected to the pressure within the enclosure. The pistons 2 drive the shaft 7 via links 9 and a plate 6 rotatably mounted on an inclined portion of the shaft 7. A rotary distributer valve 17 having arcuate grooves 18, 19 in its periphery is driven by the shaft 7, the grooves being connected, respectively, to the enclosure pressure through a groove 20 and to exhaust through an annular groove 21. As the valve 17 rotates two openings (not shown) linked to a numerical pressure detector communicate with the grooves 18, 19, the resulting changes in pressure enabling the detector to indicate the displacement and direction of rotation.
