Abstract

1446879 Steering valves DANFOSS AS 2 Nov 1973 [2 Nov 1972] 50934/73 Heading B7H In an hydraulic steering control valve of the kind described in Specification 1,446,880, the fluid path between the motor and the ports 6, 7, and between the ports 6, 7 and the outlet 4, includes respective axially extending passages 53a, 53b, Fig. 3, and 61, Fig. 6, embedded within the structure of the inner valve element 17. In a first form of construction the inner valve element 17 has an outer valve tube 15 having apertures forming the radial ducts and an inner closure tube 16, the axial ducts 53a, 53b, 61 extending along their interface. In another construction, Fig. 10, the axial and radial duets are formed by bores, the end faces of the axial bores 161, 153 being closed off by the end face of the steering shaft 114. As seen in Fig. 1 the inner tube 16 is shorter than the outer tube 15 of valve element 17 and an end 26 of universal joint shaft 23 is securely connected by a pin 27 to the outer valve element 18, the pin 27 extending through a pair of diameterically opposed apertures (not shown) in the inner sleeve 17. The other end 24 of shaft 23 engages by a pin 25, in channel-like widened portions of cavity 22.
