Abstract

1,104,424. Valves. SLOAN VALVE CO. 7 May, 1965 [13 Aug., 1964], No. 19472/65. Heading F2V. A flush control valve includes a differential piston 20 held on its seat 11 by the pressure at the inlet 6, a passage 19 extending through the piston and having a maximum dimension which is greater than the transverse dimension of an elongated liquid-admission gap between a sediment baffle 40 and the piston and a crosssection which is smaller than that of the gap, and a relief valve 53 which may be manually opened by a handle 60 to cause the piston to become unseated. The liquid admission gap may have a transverse dimension of 0À005 inches formed by the gaps between two axially spaced circumferential series of ribs to which the baffle is press fitted. A further series of ribs on a press-fitted insert 25 provide a gap of 0À0235 inches through which the liquid may enter a chamber 44 above the piston after flowing through an orifice of 0À021 inches diameter in the passage 19. When the handle 60 is pressed inwardly against a spring 64 to tilt a stem 51, the liquid in the chamber 44 escapes between the valve 53 and its seat 31 to allow the piston to be lifted by the inlet pressure. The valve is closed by a spring 56 and pressure builds up above the piston 20 to re-engage it with its seat. If the handle 60 is still held in the inward position the stem 51 is lifted freely inside the relief valve so that the latter does not open. A seal 65 retained by a projection 66 is provided for the handle 60 and a reinforced rubber or leather packing ring engages the piston skirt. The piston assembly may be of plastics material and the remaining parts of the valve of brass.
