    Abstract: The present disclosure is related to a valve assembly. The valve assembly includes a housing defining an inlet port and an outlet port.

The valve assembly includes a valve element at least partially located within the housing and movable along the longitudinal axis between a first position in which the outlet port is closed and a second position in which the outlet port is open. The valve assembly includes a biasing member located within the housing and configured to bias the valve element to the first position. The direction of movement of the valve element from the first position to the second position is generally opposite to the first direction.
