Claim:
1. A vented pressurized gas-powered actuator comprising: a housing having a proximal end, an annular shaped distal end wall for retaining a piston, an outer surface, and an inner surface, wherein the inner surface, the outer surface, and a central longitudinal axis extends between the proximal end and the annular shaped distal end wall, wherein the annular shaped distal end wall is integrally formed with the outer and inner surfaces of the housing; a reinforcing cap having a base and an annular side wall, the base defining an opening, the annular side wall extending from the base in a direction orthogonal to the base, the reinforcing cap being fixedly coupled to the housing such that the base is adjacent the annular shaped distal end wall, the annular side wall is coupled to a portion of the outer surface of the housing that lies in a plane parallel to the central longitudinal axis of the housing, and the opening defined by the base of the reinforcing cap is aligned with an opening defined by the annular shaped distal end wall of the housing; and at least one vent groove extending from the inner surface in a direction away from the axis, the at least one groove having a first end spaced apart from a first plane extending perpendicular to the axis, and a second end spaced apart from a second plane extending perpendicular to the axis, wherein the second end is closer to the second plane than to the first plane.
