Title: Improvements relating to vehicle suspension systems and pumps for such systems
Inventor: WILKINS DOUGLAS BRYAN
IPC: B60G13/14
Filed: 1964-10-24
Abstract: 1,110,220. Vehicle suspensions. GIRLING Ltd. 25 Oct., 1965 [24 Oct., 1964], No. 43448/64. Heading B7D. [Also in Division F1] In a motor vehicle suspension, a telescopic hydraulic strut 1 is connected to a pump 2 by a pipe 14 and an annular device 9, to which the interior of the strut is connected by passages 7 and 11, normally closed by a valve member 6, and controlled by non-return valves so that upon expansion of the strut, fluid may be exhausted through the outlet 11, and upon compression of the strut, may be admitted through the inlet 7. The pump comprises a piston 17 which reciprocates in a cylinder 26 and has an open interior 24 connected by radial passages 23 to an annulus 22 which, at bottom dead-centre, registers with a connection 19 to a fluid reservoir. The top of the cylinder 26 is separated by a diaphragm 27 from a gas spring 28 which is compressed by the fluid in the cylinder 26 during the upward stroke of the piston. If the inlet 7 is closed, the volume of fluid trapped will reciprocate with the piston. At the top dead-centre position, annulus 22 registers with an annulus 21 connected to the pipe 14, and if the inlet 7 is open, the spring 28 will expand and force liquid into the strut. At the position of the strut where outlet 11 is open, fluid escapes to reservoir through the piston 17 at its bottom dead-centre position. In a modification, Fig. 2, the pump piston reciprocates within a cylinder 18 and is separated by a light spring from a plunger member 42 which bears against a cap 39 which slides upon the cylinder 18 and is urged to the left by a spring 41. The mechanism is enclosed in a housing 36 which is connected to a fluid reservoir and is connected to the interior of the cylinder 18 through a passage 19 which is closed when the piston travels to the right, liquid from the interior of the piston being expelled from the interior of the piston through passages 31, 32, 23 into the telescopic strut. If the latter is closed off, however, the liquid trapped in the cylinder 18 urges the plunger 42, and thereby the cap member 39, to the right, against the pressure of spring 41 and the volume of liquid reciprocates with the piston. In a further modification, Fig. 4, the piston 17 is acted upon by a tappet 46 and the inlet is through a non- return valve 47. When the working space 26 is full of fluid under pressure the diaphragm 27 remains stationary and the tappet 46 is reciprocated idly. The gas springs in Figs. 1 and 4 may be replaced by mechanical springs and the coil spring of Fig. 2 may be replaced by a gas spring. A single pump may supply a number of suspension struts each having its own valve means or the system may include a single valve for controlling more than one strut. With the pumps of Figs. 2 and 4, a separate return live from the suspension strut is provided and the inlet and outlet 11 and 7 are isolated from one another.
