Abstract

1,168,867. Hydrauhc pumps. BORGWARNER CORP. March 1, 1967 [March 7, 1966], No. 9761/67. Heading F1A. To relieve the starting load on a motor driving a pump the output of the pump is by-passed until the motor has attained operational speed. The bypass valve 73 is loaded by adjustably compressed springs 74, 75 and seats on a member 77 which is also subjected to the pressure in the pump outlet 50, so that as the pressure rises the member 77 moves into seating engagement with the valve 73, movement being damped by flow through the passage 83 from chamber 82. The pump is also provided with a variable pressure relief valve 33 the spring pressure on which is adjusted by a lever 20 which also controls the motor switch 22.
