Abstract

216,410. Lyall, J. Aug. 29, 1923. Economizer valves and valve-gear.-In mechanism of the kind described in Specification 16101/13, the valve is constructed so that on the spindle fracturing the valve opens and remains open, and the gear is modified to ensure normal rapid closing of the valve. The valve a is arranged vertically, has a hollow spindle 1 connected to a piston d<1> provided with leakage ducts 6 and working in a cylinder d, and has therein a coaxial spindle 2 connected to the gear and carrying valves 4, 5 thereon which register through lost motion with seats on the valve a. On moving the spindle 2 downwards, the valve is first balanced on valve 4 leaving its seat, the leakage ports are then closed, and the valve a moved by the gear. On moving the spindle 2 upwards, the ports 6 are opened to unbalance the valve, the valve 4 is closed, and the valve a closed by fluid entering the passage c<2>. The lever f, f<1> is straight and slotted to engage rollers 13 on the spindle e, and levers k and f<1> have interengaging concave and convex surfaces 14, 15 respectively which coact to seat the valve a quickly. The flanges 9, 10 are arranged at right angles and a lug 11 is provided to carry a link of a parallel-motion which may operate lever h.
