Abstract

987,832. Valves. DAIMLER-BENZ A.G. Aug. 23, 1963 [Sep. 5, 1962], No. 33528/63. Heading F2V. [Also in Divisions B7 and F1] A double valve 1 for delivering hydraulic fluid supplied through an inlet union 2 to two outlet unions 4, 6, comprises a spring-loaded piston 11 controlling the flow of fluid to the union 4, and a needle 19 co-operating with a bore 20 in the piston 11 to control the flow of fluid to the union 6. The needle 19 is secured to a piston 16 slidable in a vented space 14 and urged by a spring 15 to the position shown, where it partially closes the bore 20. When a valve, not shown, connected to the union 6 is closed, pressure in the union 6 builds up and is communicated through a passage 7 and plugged bores 21, 22 to the underside of the piston 16 which raises the needle 19 to allow flow to increase through the bore 20.
