摘要
A sleeve (16) carries a main membrane (77) at its lower end and is open at its upper part to receive a control mechanism whose operation causes functioning of the valve. A cup washer (61) defines the upper end of a chamber containing a spring (63). The sleeve (16) has its wall defined by upwardly extending fingers (25) with a space between adjacent fingers. Each finger has an inwardly extending tooth. The fingers are sprung apart to insert the washer (61) and the teeth then retain it.
