Screw 10 bears on the diaphragm through a spring 12, and the upstanding pin 30 of the valve (Fig. 2, not shown) engages the diaphragm directly. The housing is formed in three parts 1a, 1b, 2, and parts 1b, 2 are secured together by resilient U-shaped rod (14) (Fig. 3, not shown). The space 7 above diaphragm 9 is substantially closed and full of air. |
