Abstract

883,570. Interconnected valves. BAHCO A.B. May 25, 1960 [May 26, 1959], No. 18510/60. Class 135. Two spring-loaded balls 22, 22A in a reversing valve are each movable between a pair of seats by a separate spindle, the spindles 30, 30A being parallel to the rotational axis of a camdisc 41. With the valve in the position shown, pressure fluid from a conduit 15 flows through the seat 27, ducts 33, 38, a groove 36, a bore 35 and a connection 34 to one side of a ram piston while exhaust from the opposite side of the piston flows through a connection 37, bore 35A, ducts 39, 40, bores 31A to an annular space 30A communicating with an outlet connection (not shown). When the cam 41 is actuated, the positions of the balls are reversed so that the conduit 15 supplies pressure fluid to the connection 37 through the duct 40 while the connection 34 communicates with the outlet connection through the now open seat 27A. The spindles and their guides 28, 28A, which are screwed into the valve body are fitted with 0-rings.
