Abstract

1,063,725. Reciprocating pumps. OSWALDS & RIDGWAY Ltd. March 1, 1966 [March 24, 1965], No.12442/65. Heading F1A. In a swash plate pump, the pistons 4 are held in engagement with the swash plate 1 by a plate or spider 10 pivotally mounted on a sleeve 11 spring biased towards the swash plate. A stabilizer pin 8 is slidable in a bearing 16, 17 fixed to plate 10, to prevent rotation of plate 10. Each piston 4 has part-spherical faces 3a, 3b engaging the swash plate 1 and a thrust washer 15 mounted on plate 10. Cylinders 5 project through a bulkhead 7, and are screwed into a cylinder block 6, and locked in position by a nylon pellet 25 and grub screw 26. Sealing rings 18 and 20, and a leakagecollecting groove 22 connected to passages 23, 24, are provided.
