Abstract
1,225,295. Vehicle suspension. GENERAL MOTORS Ltd. 3 July, 1969 [11 July, 1968], No. 33035/68. Heading B7D. [Also in Divisions F2 and H1] A pressure responsive relief valve and switch assembly for controlling an electrically driven compressor in a motor vehicle air suspension system, comprises a piston 50 movable against a spring loading 46 by fluid in the system, to open a relief port 14, and an over-centre spring 64 passing through an aperture 62 in the piston so as to be operable by movement of the piston when the air pressure reaches the required value, and prior to opening of the port 14, to open the contacts 74 of the switch and stop the compressor.
