ABSTRACT:
A valve for adjusting the closing speed of a door closer includes a generally cylindrical valve member having a tubular portion and a solid portion. The valve member is received with sliding contact in a blind-end bore of a valve body. The wall of the tubular portion of the valve member has an opening which is positionable into communication with an inlet conduit provided in the valve body in such a way that an axial adjustment of the valve member changes the cross-sectional area of the passage created between the inlet conduit and the opening. A body of elastic foam material with closed-wall cells is arranged in the interior of the tubular portion and is placed across the opening. In operation, fluid flowing through the valve applies pressure to the body and presses it away from the opening, so that the fluid can flow between the wall of the tubular portion and the body of elastic foam material without creating a hissing sound.
