Abstract
396,497. Hydraulic shock-absorbers. ELLIOTT, A. G., Wickesfield, West Wittering, near Chichester. April 12, 1932, No. 10467. [Class 108 (iii).] In an hydraulic shock-absorber particularly for vehicles the passage of liquid from a compression chamber or chambers, formed for example between the ends of a double piston b and its cylinder, is controlled by a valve e<4> or valves in the communicating passages e<1> and e, e<2>, e<3>, the resistance of a spring f acting on the valve being varied automatically by varying the pressure in one or more variable pressure chambers, formed between a stepped piston g and its cylinder, to which liquid is delivered by one or more pumps operated by an oscillating member of the shock absorber. One end of the valve e<4> may be reduced at f<1> to provide for a greater compression of liquid at one end of the cylinder than at the other, and consequently a greater resistance to movement between the axle and chassis frame in one direction than in the other. The pump comprises a plunger h<2> having teeth h<3> meshing with teeth h<4> on the shaft c<1> of the rocker arm c which operates the piston b and is connected to the axle. In operation, movement of the plunger h<2> sucks oil through a spring- pressed non-return ball-valve i<5> and forces it, with a pressure varying with the movement of the rock-shaft, through a similar valve j<3>, pipe j<7>, union j<8>, and passage j<10> to the space behind the piston g from which it escapes around the piston and passes to an oil reservoir open to the space between the ends of the piston b. The liquid may be pumped directly into the variable pressure chamber from one or more of the compression chambers by the oscillating piston itself. According to the Provisional Specification the variable pressure chamber is connected by a pipe with another compression chamber which is adapted to vary the pressure on the controlling valve. Reference is made in the Provisional Specification to Specification 372,445.
