Abstract
A solenoid valve 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 includes a vacuum booster diaphragm and a grommet attached to the vacuum booster diaphragm. A vacuum booster assembly includes the above-described solenoid valve, includes primary and secondary diaphragms, and includes the above-described grommet attached to the secondary diaphragm, wherein the secondary diaphragm is the above-described vacuum booster diaphragm.
