Abstract
A fluid pressure regulator is provided having a housing with an inlet and outlet for fluid, a valve located movably inside the housing and provided with a fluid transport member to allow passage of fluid from the inlet to the outlet. The regulator also has a pressure setting member and a space defined by one end of the valve and an end wall of the housing. The valve is moveable relative to the housing in response to a change in pressure within the space between a first position which at least partially aligns the fluid transport member with each of the inlet and the outlet and a second position in which there is no alignment of the fluid transport member with at least one of the inlet and the outlet. A passage is provided in open communication with the space and one of the inlet, the outlet, and the transport member. Methods of using the pressure regulator are also provided.
