Abstract

151,475. Denison, G. H., and Brown, S. C. Oct. 2, 1919. Valve-gear &c.-In a rotary oil pump of large capacity for hydraulic testing machines, the control member of the pump is regulated to produce rapid reversal of the pressure fluid by means of the power supplied by a small auxiliary pump under hand control. The machine to which the apparatus is applied is described in Specification 121,013, [Class 69 (ii), Hydraulic presses &c.], and as shown in Fig. 1, the pump 6 supplying oil under pressure to the cylinder 1 is controlled by the movement of a spindle 7 attached to the piston 8 of a small cylinder 9 which receives oil from an auxiliary pump 10 controlled by means of a hand lever 11. In a modified arrangement, the hand lever 11 is pivoted to the control spindles 7, 12 of the pumps 6, 10 in order to give complete control of the large pump by automatically neutralising the stroke of the small pump.
