1. A manifold assembly comprising:
a solenoid valve; a manifold having an inlet bore and an outlet bore; and a check valve having:
a first end configured to directly mate with the solenoid valve, a first inlet passage and a second inlet passage, both the first inlet passage and the second inlet passage being aligned parallel to a central axis of the check valve and both the first inlet passage and the second inlet passage being configured to provide a conduit for a fluid to flow from the inlet bore to the solenoid valve;an O-ring, a poppet, and a spring disposed in a check valve outlet bore, the check valve outlet bore being threaded to accept a follower configured to retain the poppet and the spring within the check valve outlet bore, the check valve outlet bore being disposed between the first inlet passage and the second inlet passage and extending further out from the check valve than the first inlet passage and the second inlet passage, the check valve outlet bore being in alignment with the central axis of the check valve and between the first inlet passage and the second inlet passage and the first inlet passage and the second inlet passage extending further along the check valve outlet bore than the O-ring and poppet, the O-ring, the poppet, and the spring being disposed downstream of the solenoid valve and configured to allow a unidirectional flow of the fluid from the solenoid valve to the outlet bore, the spring biasing the poppet to seal against the O-ring; anda second end configured to directly mate to the manifold, the second end having an outlet disposed downstream of the O-ring, the poppet, and the spring and the outlet being in alignment with the central axis of the check valve, the outlet being in fluid communication with the outlet bore. |
