Abstract

A fuel pump vent-relief valve for venting a vapor pressure less than a working pressure and relieving the fluid pressure when in excess of a predetermined relief pressure includes a valve body having an inlet passage (300), an outlet passage (296), and a valve bore (294) containing a ball valve (292) and a tubular valve (302), the tubular valve and the valve body cooperating to define a relief passage between the inlet passage and the outlet passage. A first spring (306) between the ball valve and the tubular valve biases the ball valve towards the inlet passage and the tubular valve towards the outlet passage, the ball valve being adapted to cooperate with the inlet passage to establish a vapor bypass passage therebetween when the ball valve contacts the inlet passage, the tubular valve having a vent passage (314) therethrough adapted to be closed by the ball valve. A second spring (310) between the tubular valve and the outlet passage biasses the tubular valve towards the inlet passage, to normally close the relief passage. Thus, vapor pressure is vented through the bypass passage and the vent passage until the fluid pressure overcomes the first spring to cause the ball valve to close the vent passage. Subsequently, a rise in fluid pressure above a predetermined relief pressure causes the tubular valve to move towards the outlet passage to open the relief passage. The bias on the ball valve may be provided by gravity.
