ABSTRACT:
A check valve for controlling flow between a low-pressure reservoir and a source reservoir has a pin and an associated diaphragm. The pin has a shaft portion which is attached adjacent to the low-pressure reservoir and a closed head portion. The shaft of the pin has a central channel which opens into the low-pressure reservoir and is connected to the outer surface of the pin by at least one opening in the pin. The diaphragm is made of an elastomeric material and is disposed to tightly fit around, and bias against the surface of the pin. The diaphragm seals around the opening in the pin and is elastically deformable by a predetermined positive pressure to define a pathway from the high-pressure source into the opening in the pin and ultimately into the low-pressure reservoir.
