Title: Improvements relating to pressure responsive valves
IPC: F01M1/16
Filed: 1945-02-23
Abstract: 594,787. Fluid-actuated valves. SULZER FRERES SOC. ANON. Feb. 23, 1945, No. 4585. Convention date, Feb. 24, 1944. [Class 135] A pressure responsive valve for use in an engine regulating or lubricant circuit including a filter comprises a differential piston 6 controlling a relief passage 14 from the circuit, and subjected to the pressures before and after the filter 9 so that the pressure before the filter at which the valve responds increases with increasing filter resistance. As shown, lubricating points 11 of an internal combustion engine 1 are fed by a pump 3 discharging through a chamber 5 of the valve, the filter 9, and a conduit 10. The conduit 10 is connected to a chamber 7 where the pressure acts on the smaller diameter 6b of the piston, the sum of this pressure and that in the chamber 5, which acts on the larger diameter 6a of the piston, being balanced by a spring 8. Thus, when the resistance to flow of the filter is large, e.g. with cold oil, the pressure in the chamber is necessary to open this chamber to the relief passage will be greater than with hot oil, owing to the filter outlet pressure acting in the chamber 7 being less.

Abstract: 286,442. Gehersky, W. W. Feb. 21, 1927. Vehicle lamps, directing. - An electric spot-light 54 is carried by a shaft 51 mounted in a casing 43 rotatable in a cylinder 45, the shaft and casing being adapted to be rotated by operating a handle 25 within the vehicle, and switches 67, 75 are provided for automatically lighting the lamp when it is moved into predetermined positions. The handle 25 is connected by a flexible coupling 36 in a flexible casing 16 with a rod 37 mounted loosely in the hollow shafts of a worm 41 and a gear 39. In the normal position, a spring-pressed ball 30 engages a recess 27 in the handle. When the latter is pushed inwardly to engage the ball 30 in a recess 29, a tooth 38 on the rod 37 engages the end 42 of the worm shaft, which may then be rotated by turning the handle so as to actuate the shaft 51 for turning the lamp in a vertical plane. When the handle is pulled outwardly to engage the ball 30 in a recess 28, the tooth 38 engages the gear 39, which may then be rotated for adjusting the lamp in a horizontal plane, the gear 39 being connected by a twinpinion 62 with a pinion 57 secured to the casing 43. The gear 39 is held normally by a spring 65 in engagement with a tooth on the underside of the pinion 57. The switches 67, 75 are arranged in parallel. The switch 67 comprises a band 68, secured adjustably on the shaft 51 and carrying an insulating block 70 adapted to break the circuit between the band 68 and a spring terminal 71 carried by an insulator 73 on the casing 43.

Abstract: 1287726 Centrifugal vacuum pumps; jet pumps I C JENNINGS 2 Feb 1970 [3 Feb 1969] 4882/70 Headings F1C and FIE, A high vacuum pumping system has a low vacuum pump 10, Fig.1, e.g. of the liquid-ring type, and a high vacuum pump 58 e.g. of supersonic ejector type. During evacuation of a container, e.g. a condenser, via suction line 16 the pump 58 is initially isolated by valves 20, 22 as shown. However, when a predetermined vacuum within the container is reached (e.g. 26 inches of mercury) the valve 22 is lowered on to alternative seat 32 and the valve 20 is raised whereby the pump 58 is rendered effective and operates in series with the pump 10. A stream of fluid is introduced by the pump 58 from a relatively highpressure source. The valves 20, 22 are hydraulically or, as shown, pneumatically actuated by piston and cylinder units 34, 38 and 36, 40. Compressed actuating-air is delivered to and exhausted from the cylinders 38, 40 via a control device 64 having a double-acting control piston 62 responsive to the position of a control valve 70 movable by a solenoid 50 energized through a diaphragmoperated vacuum switch 52.
