CYLINDER COVER FOR STEAM POWERED NAILING GUNS

摘要

The invention relates to a cylinder cover for a cylinder of a piston mechanism. In certain embodiments, the cylinder cover includes a cylinder cover body, a valve plate, and a one-directional valve. The cylinder cover body has an exhaust port, and an oil intake. The exhaust port and oil intake are disposed on outer circumference of the cylinder cover body. The one directional oil valve is formed by a compression spring and a ball. An inner end of the oil intake is connected to the compression spring through the ball and the ball is disposed between one end of the compression spring and the inner end of the oil intake. The valve plate is retained on an inner wall of the cylinder cover body by a retaining nut. The cylinder cover further has an auxiliary heating rod inside cylinder cover body for pre-heating cylinder cover to a predetermined temperature.
