Abstract

See full text

A sliding screen valve for controlling fluid flow comprises a multi-apertured valve plate (50, 90) configured for sliding movement relative to a multi-apertured valve seat between closed and open configurations and comprises an array of apertures (60, 100) separated from one another by elongate interstitial elements angled at between 15 to 45 degrees from the axis of motion. The valve plate may be operatively connected via an actuator frame (274) controlling its movement to an actuator for sliding movement relative to the valve seat, and may be connected to the actuator via a resilient support element (272) configured to allow a floating movement of the valve plate normal to the valve plate. Initiation or termination of the sliding movement may be damped by at least one damping mechanism. The screen valve may be configured for lateral reciprocating movement and be used in gas compression and/or expansion equipment such as piston compressors or expanders.
