Abstract
2051. Smith, W. Jan. 26 Lifts.-An automatic valve for use with hydraulic lifts and similar machines is provided with a spring-loaded lift valve, which, as the pressure required in the machine increases, is set to open and admit high - pressure liquid through the medium of an intensifier. The Figure shows the construction of the valve arranged so as to be actuated by the pressure from an intensifier, which is adapted to rise as the work progresses and is so connected that it is only put into action when the low-pressure valve is opened. The lowpressure pipe 12 leads to the press, and a branch from it leads to the intensifier 14, the hollow piston of which forces liquid at higher pressure through the pipe 18 to the underside of the spring-loaded valve 20, which is thus lifted near the end of the pressing &c. operation to allow the high-pressure fluid to complete the work commenced by the low-pressure fluid.
