Abstract
A poppet type valve assembly comprising a body having an axial bore extending therethrough and defining a fluid flow passage and an internal, generally cylindrical valve chamber. Seat means are carried in the bore adjacent a first end of the valve chamber to define a valve seat coaxial with the bore. A poppet valve member is mounted in the chamber for movement axially thereof toward and away from the seat. Extending axially of the chamber is a coil spring for maintaining the poppet valve member under a continual bias toward the seat. Valve stop means are provided for limiting movement of the poppet valve member in a direction away from the valve seat. The valve stop means including a central body portion having a plurality of legs which extend radially between a shoulder and the coil spring. A central body portion of the stop extends axially into the coil spring toward the poppet valve member a distance such that movement of the poppet valve away from the seat is stopped before the coil spring is fully compressed.
