Abstract

A spring-loaded double-ended check valve assembly 17 is provided for use in the outlet chamber 14 of a dispenser for spraying liquids. The entire assembly 17a - 17f including opposite end discs 17b, 17c and the S- shaped spring 17a, is made in one piece and is easily moldable from plastics material thus effecting ease of manufacture and assembly into the sprayer, reduced labour and material costs and affording the reliability of a unitary member. <IMAGE>
