Valve for cryogenic fluid
First Claim
1. A valve comprising:
- a valve housing including an inlet, a first outlet and a second outlet, the housing having an inlet chamber, a first outlet chamber and a second outlet chamber that are adapted to receive fluid from the inlet and deliver the fluid to the first and second outlets, the inlet chamber and the first outlet chamber being fluidly coupled by a first aperture defined by a first valve seat, the inlet chamber and the second outlet chamber being fluidly coupled by a second aperture defined by a second valve seat;
a first valve actuator cooperating with the first valve seat to seal the first outlet chamber from the inlet chamber;
a second valve actuator cooperating with the second valve seat to seal the second outlet chamber from the inlet chamber;
a check valve disposed in the valve housing to prevent fluid flow from the housing through the inlet; and
a filter disposed in the housing between the inlet and the first and second outlets to remove debris from the fluid.

Abstract
A valve for cryogenic fluids that divides incoming fluid into separate outlets. The valve prevents the inadvertent leakage or reverse flow of fluid through the valve using a swing-type check valve, and may also remove undesirable debris from the fluid. The valve comprises a valve housing and at least one valve actuator. The housing includes an inlet and at least one outlet, and has an inlet chamber and at least one outlet chamber that are adapted to receive fluid from the inlet and deliver the fluid to the outlet. The inlet chamber and the outlet chamber are fluidly coupled by a valve aperture that is defined by a valve seat. The valve actuator cooperates with the valve seat to seal the inlet chamber from the outlet chamber. In one embodiment, the valve includes a check valve that is pivotally mounted in the valve housing to prevent fluid flow from the valve housing through the inlet. In another embodiment, the valve includes a pair of outlets, a pair of outlet chambers and a pair of valve actuators. In a further embodiment, the valve includes a filter that is disposed in the housing between the inlet and the outlets to remove debris from the fluid.
