In a large-diameter actuator cap of a known general kind having internal transverse walls 13 with the actuator 11 between them, the lower edges of these internal walls are notched (15, 16,) to engage over the rim of a standard valve mounting cup and give added stability and strength. This allows the cap to be made with thinner walls, and therefore less total material, than hitherto without detracting from its ability to meet minimum requirements on stiffness and strength. <IMAGE> |
