Abstract

559,883. Relief valves. DAVIS, W. L. May 7, 1942, No. 6188. [Class 135] A relief valve for liquid fuel pumps has a liftvalve member carried by a hollow piston 17 slidably mounted in the casing and sealed against leakage by means of a flanged flexible cup 18 attached to the piston by an inner sleeve 16 and a flange 19 and with its flange clamped between two parts of the casing. The flange has a rib 39 adapted to engage mating recesses on a removable cover 5 and an inner guide plate 26 for the piston clamps held in place by the cover 5. The flange 19 is formed integrally with a spindle 41 the upper part of which slidably engages a depending guide sleeve 42 formed on the cover 5 while the lower part is reduced and screw threaded to receive a nut 13 adapted to hold a rigid washer 11 and a resilient washer of synthetic material against the end of the piston. Both these washers co-operate with an inclined surface on a seat 10 to control a byepass connection between the pump outlet 28 and pump inlet 29. A spring-loaded valve 8 permits liquid to pass from the pump inlet to the pump outlet when the pump is out of action. The principal valve is loaded by a spring 20 arranged between the flange 19 and an abutment slidably mounted on the guide 42 and adjusted by a screwed spindle 34 rotatably mounted in the cover and engaging a nut 22 having projections passing through slots in the guide 42 into engagement with the abutment 21. The screwed spindle is held in a recess in the cover by a flange engaged by a ring 25 which is a press fit in the recess. A screwed jamb ring 24 secures the spindle in its adjusted position. When it is desired to relate the maximum fuel pressure to the pressure in the air intake to a carburetter the plug 32 is removed and a pipe connection established between the air intake and the interior of the flexible cup.
