Abstract

218,805. Blakeborough, J. E., Broadhead, J. B., and Wood, T. June 1;'1923. Valves controlled by pilot or relay valves.-A fluid-operated valve carries a leaky piston of greater area open on its lower side to the inlet pressure, and having an axial bore extending through it, which is controlled by a hand or float operated auxiliary valve. to actuate the main valve. The main valve c carries a piston c<1> of larger area, moving with clearance in the cylinder a<3>. An adjustable leak j is also provided. The upper end of the axial bore d is controlled by a valve g<1> which is operated by a hand or float lever k. When the valve g<1> is closed, the valve c is retained on its seat by pressure, but when the pressure in the space a<4> is released by opening the valve g<1>, the valve c is opened by excess of pressure below the piston. The valve c may be positively held open by the upper side of the valve g<1> bearing against a screwed plug i.
