Abstract
An outlet valve for a gas compressor includes a valve seat 1 formed with several rows of apertures 16, a thin flat valve plate 2 having several spaced spring tongues overlapping the apertures, a limit plate 4 overlying the valve plate, and a pressure member 5 above the limit plate. To control and damp the movement and flutter of the valve plate it is frictionally gripped between the limit plate 4 and the valve seat, and springs 15 press the limit plate against the valve plate. Both the valve plate and limit plate can move towards and away from the pressure member 5, this movement being restricted to a fraction of a millimeter by spacer bushes 14 and spacer studs 7. The underside of the limit plate 4 is concavely curved to correspond to the natural bending curvature of the thin valve plate.
