Abstract

1,120,321. Eccentric-rods. DOWTY TECHNICAL DEVELOPMENTS Ltd. 11 Nov., 1965 [23 Nov., 1964], No. 47493/64. Heading F2K. [Also in Division F1] In an hydraulic pump or motor comprising at least one pair of cylinders extending in different directions from a shaft and having pistons associated with a single eccentric bearing member on the shaft, each piston is secured to a connecting rod 58 having a hollow cylindrical bearing rotatably carried on the bearing member each cylindrical bearing having a first part 67 adjacent the connecting rod 58 which is wider than a second part 68 opposite the connecting rod, the arrangement being such that the first part 67 is adjacent the second part 68 of another hollow cylindrical bearing and the second part 68 is adjacent the first part 67 of the other cylindrical bearing. A lubricating pump on the shaft supplies the shaft bearings and the bearing grooves 69, 71 which are fed from passage 26 during the pressure stroke.
