Abstract

544,824. Valves. COCKBURNS, Ltd., RODGER, J., and GRANT, T. Nov. 25, 1940, No. 16861. [Class 135] In a pressure fluid control valve in which the valve stem 15 carries a piston 18 movable in a cylinder 19, the latter is removably accommodated with external circumferential clearance in a cylindrical bore 20 within the valve chest 10 and at its inner end has a boss 21 for guiding the valve stem. The cylinder is prevented from rotating by a pin 24 and is held between an annular abutment 22 on the chest 10 and a cover 13. The chamber 27 above the piston 18 is connected to the inlet 11 through passage 26 and valve 28. The other side 30 ot the piston 18 is connected to exhaust through a passage 29 provided with a valve (not shown). When a nut 31 having a handle 32 is turned in the direction to permit opening of the valve 16, a collar 37 on the nut 31 engages a bell-crank lever 33, 34, and opens the valve 28. Pressure fluid leaks into the chamber 30. When it is desired to shut the valve 16 rapidly the valve in the passage 29 is opened to exhaust the pressure in the chamber 30. Specifications 19084/14, 2524/15 and 105,695, [all in Class 135], are referred to.
