Abstract

A valve plate 3 is loaded by a spring 4 towards a seat 2 and is guided by the arms 10 of a wire cage, the arms 9 of which act as a spring abutment. The cage is formed by two stirrups welded at their crossing point 8 and having the ends of the arms 10 bent upwardly to resiliently engage with arcuately bent portions 14 in a groove 15 of the housing. The bent portion 11 engages in a groove 12 outwardly of the seat. In a modification the ends 16 of the arms are bent downwardly towards the seat to form intermediate guides. In another embodiment the arms 10 are bent to have an arcuate portion engaged in the groove 12 and extending to the adjacent arm 10 whereat it is bent back to form an arcuate portion overlying the first and engaged in an undercut recess of the housing.
