Abstract

179,854. Flower, J. W. June 30, 1921. Closure members, piston and tubular. -A valve more particularly for use in conjunction with h haist-control valves for hydraulic cranes as described in Specification 738,529 [Class 78 (iv), Loading &c.], comprises an arrangement of ports for restraining the pump circulation and maintaining pressure fluid for slewing purposes when hoisting is not taking place. The valve body 1 is provided with inlet and outlet passages 2, 3 controlled by a sliding valve 4 which is balanced by fluid pressure in the space 8 and in grooves in the valve face. In the position shown, the valve allows unrestricted circulation of liquid to and from the pump. but if moved to the right, the outlet 3 is closed and the outlet 10 opened to allow fluid to pass to the slewing cylinder, the return flow being through the passages 11, 15, and 13 to the outlet 3. The valve may be set in an intermediate position so that the slewing operation may be regulated.
