Abstract

A constant flow valve includes a housing (1) containing a fluid flow passageway (10), a resiliently-biased piston (18) located in said passageway and mounted for movement in response to changes in the differential fluid pressure across the valve, and a throttle member (38) located in the passageway in the vicinity of the piston to define a throttle passageway between the piston and the throttle member. The throttle passageway (43) is tapered and defines at its point of minimum size a throttle orifice (44). The size of said throttle orifice varies in use with movement of the piston (18) in response to changes in the differential pressure, such that the flow rate of fluid through the valve is substantially constant.
