摘要

A solenoid valve (10) includes a valve housing having first, second, and third valve ports, an actuation rod, a first tip valve actuated by the first end of the actuation rod to allow or block fluid passage through the first valve port, and a second tip valve actuated by the second end of the actuation rod to allow or block passage through the second valve port. A vacuum booster diaphragm subassembly (76) includes a vacuum booster diaphragm (78) and a grommet (80) attached to the vacuum booster diaphragm. A vacuum booster assembly (98) includes the above-described solenoid valve, includes primary and secondary diaphragms (108 and 116), and includes the above-described grommet attached to the secondary diaphragm, wherein the secondary diaphragm is the above-described vacuum booster diaphragm.
