Title: Improvements in or relating to valve devices for controlling the filling of tanks and like receptacles with liquids
Inventor: FRASER JOHN
IPC: F16K31/34
Filed: 1956-09-28
Abstract: 823,979. Fluid-pressure servomotor-control systems. AVERY-HARDOLL Ltd. Aug. 2, 1957 [Sept. 28, 1956], No. 29730/56. Class 135. A valve device for controlling the filling of tanks with liquid comprises a main filling valve opened by the pressure of liquid supplied to the tank and closed by liquid pressure built up in a control chamber, and a pilot valve controlling the escape of liquid from the chamber, the pilot valve comprising a body formed with a liquid passage in which are arranged in series at least two valve seats engaged each by a corresponding spring-urged closure member having a substantially spherical closure surface, and a pin movable in this passage in response to changes of liquid level in the tank to displace said closure members successively from their seats as the liquid level falls and to release the closure members successively for re-engagement with their seats as the liquid level rises. As shown, a main filling valve 12 at the bottom of a tank 10, 11 is closed stepwise during a filling operation by the pressure of liquid in a control chamber 31 which is supplied with the inflowing liquid through a stationary tube 32, outflow from this chamber being controlled by a pilot valve 18. The pilot valve comprises a body 33 having three oblique bores 36, 39, 42 which house three spring-loaded ball-valve closure members 44 obturating corresponding seat openings from the bores, the seat openings being connected together for series flow by a vertical through flow passage 34, and the lowest seat opening having a permanent leak port 49. An actuating pin 48 connected to a float 19 displaces the ball closure members successively from their seats on falling of the float and allows them to re-seat on rising of the float. On rising level in the tank, closure of the lowest ball so restricts outflow from the control chamber that the main valve partially closes to a position where the outflow is balanced by a restricted inflow through tube 32; whilst on a predetermined full level being reached, closure of the second ball causes the main valve to close completely. The third or top ball constitutes a safety closure device which functions similarly to the second ball in the event of failure of the second ball to operate. In alternative embodiments, one of the two upper ball closures may be omitted; or the lowest ball closure associated with the leak port 49 may be omitted in which case the main valve closes completely in a single step. Specification 732,282 is referred to.

Title: Improvements in power devices for operating clutches in motor vehicles
IPC: B60K23/02
Filed: 1934-10-22
Abstract: 446,014. Fluid-pressure servomotor control systems. GILLETT, E. H. J. C., 32, Marlborough Mansions, Cannon Hill, London. Oct. 22, 1934, No. 30257. [Class 135] A motor-vehicle clutch (or equivalent means for disengaging the transmission, such as the friction brake means controlling the gear trains of an epicyclic change-speed gear) is operated by a fluid-pressure servomotor controlled bv a valve 56 responsive to engine speed and by a valve 57 which is connected by a Bowden cable 21 to the accelerator so as to produce engagement, irrespective of engine speed, when the throttle opening exceeds a predetermined amount, and which is provided with a dashpot to retard its movement in the clutch-engaging direction. The clutch - operating shaft 45 carries a lever 46 engaging the servo-piston 47 which is operated by oil supplied to the cylinder 48 from the casing 22 through passages 49, 50 by a gear pump 51, 52, the driving shaft 53 of which is constantly driven from the engine. The valve 56 is operated by centrifugal weights 59 rotating with the shaft 53 and is provided with a follow-up sleeve 60 connected to the lever 46 by a stud 62. If the throttle is opened more than a certain amount, the valve 57 moves to the left and the pressure in the cylinder 48 is relieved, so as to produce clutch engagement, through passages and ports 82 ... 89. If the throttle opening is less than this predetermined amount, the ports 86, 87 are closed and the valve 56 effects the control by controlling further relief ports, the effect of the follow-up sleeve 60 being that, within the operative speed range, the clutch is progressively engaged as the speed increases. A valve 55, adapted to close the port 83, is controlled by the gearchanging means so that clutch disengagement is brought about during gear changing. The dashpot device for the valve 57, which is urged to open position by an adjustable tension spring 78, is constituted by a chamber 65 behind the valve, having an outlet passage 66 controlled by a ball-valve 73 and an adjustable valve 68. The chamber 65 is kept charged with oil through a ball-valve 69 from a trough 72, into which the port 87 discharges and to which oil is supplied from the engine-lubricating system. Specification 421,894, [Group XXIV], is referred to.

Abstract: 717,478. Cooling systems for internalcombustion engines. SICKINGER, H., [trading as MECANO SPEZIALARTIKEL FUR KRAFTFAHRZEUGE.]. Dec. 5, 1952, No. 30903/52. Class 64(3) In a closed liquid coolant circulating system for an internal-combustion engine E in which hot coolant circulates from the engine through a pipe 3 leading to a radiator 2 in which it is cooled and from which it flows through a further pipe 4 incorporating a pump 6 and back to the engine, a thermostatic valve 10 is provided in the outflow pipe from the engine and a by-pass pipe 7 permanently interconnects the suction and pressure sides of the pump in such a way that if the thermostatic valve is closed the pump operates via the by-pass pipe 7 in a closed circuit. The system operates as follows: On starting, when the coolant is cold, the thermostatic valve 10 remains closed so that no circulation can take place through the radiator 2. The coolant then circulates only within the engine block, e.g. by thermosyphon action. At the same time, owing to the pressure maintained by the pump which is constantly circulating water through the by-pass, causing also a reduction in pressure in the pipe 3, undesired opening of the thermostatic valve against its thermal bias is prevented. As the temperature in the engine block rises the thermostatic valve 10 is caused to open and so allows a small and gradually increasing flow through the radiator. The angles at which the two ends of the bypass pipe 7 enter the main flow pipe 4 are such that an ejector action is exerted on these openings and therefore as more coolant is allowed to flow through the pipes 3 and 4 and the radiator 2 so progressively less coolant is circulated through the by-pass 7.
