Valve guide for poppet valve

摘要

A poppet valve guide mechanism for use in pumps such as large piston-type pumps uses a valve guide sleeve secured to an outwardly extending base plate which has a plurality of support legs attached thereto. The guide and support assembly are retained in place by a partially tapered locking bar transversely engaged on said assembly, and arranged to seat the support legs tightly on an annular ledge formed in the pump's fluid-end chamber.
