Abstract

587,380. Swash-plate pumps. ELECTROL, Inc. Dec. 29, 1944, No. 26112. Convention date, Jan. 27. [Class 102 (i)] [Also in Group XXIX] In a multicylinder pump, the pistons 12 are actuated by a swash plate 30 mounted in a spherical seat 31 secured to a shaft 32 on which is formed a piston 53. The swash plate 30 is pressed by a spring 54 against a roller bearing race 27 that is.mounted in an inclined position on a driving shaft 22. The pump suction chamber 11c is connected to the pump cylinders by ports 11d and delivery from the pump cylinders takes place through valves 14 engaging valve seats 13 screwed into the cylinders and provided with rings 13b against which the valves 14 seat. A ball valve 41 is pressed by an adjustable spring 45 against a seat 40c connected to the pump delivery passage 16e. When the pump delivery pressure rises above a predetermined value, the valve 41 is moved on to seat 42c and liquid under pressure passes into cylinder 16c, ports 32c, 32d to the cylinder 11c to move the piston 53 and with it the swash plate 30 away from the race 27 so that the reciprocation of the pistons ceases. The valve seat 42c is larger than the seat 40c so that when the pressure falls to a lower predetermined value, the valve 41 engages the seat 40c and pressure liquid in the cylinder 11c is released through the seat 40c and port 52 and the pistons 12 are again actuated.
