Abstract
Apparatus to connect a valve stem to a valve member are disclosed. An example apparatus includes a valve stem having a laterally extending opening, a valve member having a laterally extending opening, and a coupling having adjacent one end an extension received in the laterally extending opening of the valve stem and adjacent an opposite end an extension received in the laterally extending opening of the valve member. A resilient member is located between the valve stem and the valve member.
Claims27
An apparatus to connect a valve stem to a valve member, comprising:
- the valve stem having a non-threaded constant diameter along a longitudinal length thereof, and a laterally extending opening positioned along the longitudinal length;
- the valve member having a laterally extending opening;
- a coupling having adjacent one end an extension received in the laterally extending opening of the valve stem and adjacent an opposite end an extension received in the laterally extending opening of the valve member;
- and
- a resilient member located between the valve stem and the valve member, wherein the valve stem includes a longitudinal extension disposed beyond the longitudinal length and adjacent the valve member, the resilient member flexible to enable the longitudinal extension to move toward and engage the valve member during movement of the valve stem.
A control valve having an apparatus to connect a valve stem to a valve member, comprising:
- the valve stem having a non-threaded constant diameter along a longitudinal length thereof, and a radially extending opening positioned along the longitudinal length;
- the valve member having a radially extending opening;
- a coupling having adjacent one end a radial extension received in the radially extending opening of the valve stem and adjacent an opposite end a radial extension received in the radially extending opening of the valve member;
- a resilient member located between the valve stem and the valve member, wherein the valve stem includes a longitudinal extension disposed beyond the longitudinal length and adjacent the valve member, the resilient member flexible to enable the longitudinal extension to move toward and engage the valve member during movement of the valve stem;
- and
- a housing having a longitudinal bore, wherein the coupling, the resilient member and at least a portion of the valve stem and the valve member are disposed in the bore.

- the valve member having a radially extending opening;
- a coupling having adjacent one end a radial extension received in the radially extending opening of the valve stem and adjacent an opposite end a radial extension received in the radially extending opening of the valve member;
- a resilient member located between the valve stem and the valve member, wherein the valve stem includes a longitudinal extension disposed beyond the longitudinal length and adjacent the valve member, the resilient member flexible to enable the longitudinal extension to move toward and engage the valve member during movement of the valve stem;
- and
- a retainer to retain the radial extensions of the coupling in the radially extending openings.
