Abstract

582,028. Hydraulic control valves. BROWN TRACTORS, Ltd., D., and MEADOWCROFT, F. June 15, 1944, No. 11430. [Classes 69 (ii) and 135] A combined hydraulic control and pressurerelief valve comprises a valve member e which controls the supply of pressure liquid from a supply passage c to a pipe i leading to the hydraulic actuating cylinder for operating the implement' carried by a tractor by controlling. the exhaust from passage b. The valve e is loaded to close by a spring h, acting through a lever f pivoted at f<1> and opened by manual operation of a Bowden cable g or by excess pressure of the liquid in the hydraulic system against the spring h. A non-return valve j and a restricted passage k is provided in the pipe i to regulate the rate of the exhaust of the liquid from the power cylinder.
