ABSTRACT:
A valve device for permitting a fluid to flow in two opposite directions at different rates includes an orifice body confining a flow passage. The orifice body has one end defining a valve seat. A valve member is swingingly mounted to the housing to move toward and away from the valve seat. The valve member has a hole with a cross-section smaller than that of the flow passage whereby the flow of the fluid is large when the valve member moves away from the valve seat and is small when the valve member moves toward and seats against the valve seat.
