ABSTRACT:
A valve selector including a telescoping spring capsule subassembly having a dual retainer ring arrangement for limiting the maximum extended length thereof. A cup-shaped spring retaining member has an internal groove formed near its rim and a cup-shaped spring receiving member has an external groove formed near its outer open end. The spring retaining member is partially received over the spring receiving member with the external groove axially aligned over the internal groove. A compression spring is captured between the opposed bottom surfaces of the retainer members. An inner retaining ring is received in the external groove and an outer retaining ring is received in the internal groove. The outer ring has an internal diameter sized less than the outer diameter of the inner retaining ring for providing a radial overlap condition. The maximum spacing of the spring receiving and spring retaining members is limited by abutment of adjacent axial faces of the inner and outer retaining rings.
