Abstract
1,127,650. Valves. OFFICINA MECCANICA SESTESE DI ROSSI & CRISTINA. 20 Dec., 1965, No. 53975/65. Heading F2V. [Also in Division B8] A throttle valve 24 comprises a slide 41, axially movable in a body 40, and an obturator 43 which are axially pierced at 41<SP>1</SP>, 45 and which are held in the positions shown by springs 42, 44, respectively, when there is no fluid flow through the valve. When fluid flows through the valve, the slide 41 moves to the right and then the obturator 43 is lifted off its seat in the slide, thereby increasing the passage for the fluid, Fig. 13 (not shown). Fluid then also fills an annular chamber 48 and passes to a pressure release valve 25, leading to the reservoir, whereby the pressure in the system is limited during flow through the valve. In a modification, Figs. 15, 16 (not shown), the valve is arranged, when fluid passes through the valve and moves the slide and obturator to the right, to allow the passage of fluid in a separate line (53) to a pressure release valve (54). A valve 110, Fig. 20, consists of a first section 110<SP>111</SP> which is in an hydraulic fluid line A, B and which comprises a cylinder 124 containing a slide 123 coupled to a piston 116 in a second section 110<SP>1</SP>. The second section is located in a pneumatic line, the arrangement being such that when air flows through the pneumatic line through a metering orifice in the piston 116, the piston moves to the right against the action of a spring 117 and thereby moves the slide 123 to allow flow of hydraulic fluid through the line A, B.
