摘要： An actuator end cap is provided for an actuator having a housing and a cover connected together and defining a joint therebetween. The end cap has a skirt portion disposed in overlying relation to the joint to provide a fluid-tight seal for the joint. A breather hole is formed in the side of the cover and a semi-cylindrical groove is formed on the inner surface of the skirt of the end cap. One end of the groove is disposed in communication with the breather hole in the cover and the other end of the groove is in communication with a vent hole extending outwardly through the end cap.
