Abstract

874,201. Fluid-pressure servomotor control systems; hydraulic transmission of power. NAPIER & SON Ltd., D. Nov. 26, 1959, No. 40267/59. Addition to 836,069. Classes 69 (2) and 135. [Also in Group XXVII] The system of the parent Specification is modified by the inclusion of a pump delivery control mechanism (see Fig. 1). A servo pump 43, Fig. 3, provided with by-pass relief valve 44 delivers fluid at constant pressure to the two branches 48, 49 of the valve assembly 45. Outflow is controlled by pressurizing valve 47. Connected between the branches is a servo cylinder 50 containing a spring-loaded piston 51, connected to the pump 16 by link 52, the position determining the volumetric delivery of the pump per revolution. The piston position in the cylinder is determined by the pressure difference between its left-hand and right-hand faces, which in turn is determined by the position of an inflow distributer valve 53, an outflow distributer valve 54, and a dump valve 55, all three being connected to yoke 56 the position of which is determined by a bellows 57 loaded by a spring 58. The interior of the bellows is in communication with the delivery side of the pump through line 59, with a pressure relief valve 60. Operation: a maximum pressure determined by relief valve 60 is built up by the pump 16 driven by the electric motor 15 with the two valves 29, 30 closed. As the pressure builds up, the bellows 57 expand, moving valves 53, 54 and 55 to the left so that the piston 51 moves to the left, reducing the delivery of the pump. When the maximum pressure is obtained the bellows will be fully expanded with valves 53, 54 and 55 and piston 51 in their left-hand positions. On opening valve 29, in order to start engine 12 by hydraulic motor 17, the pump delivery pressure will fall so the bellows will begin to contract. This will cause valves 53, 54 and 55 to move to the right, thereby causing piston 51 to move to the right to increase the pump delivery and restore the pressure to its previous value. Thus up to the full capacity of the pump, its volumetric delivery per revolution is automatically adjusted to maintain a constant delivery pressure.
