Title: Improved thermostatically controlled hydraulic valve
IPC: F01M5/00
Filed: 1942-06-06
Abstract: 553,892. Thermally-actuated valves. GENERAL MOTORS CORPORATION. June 6, 1942, No. 7721. Convention date, June 6, 1941. [Class 135] [Also in Group XIII] A thermally-actuated valve particularly adapted for use with oil coolers on aircraft, comprises a rotatable cylindrical member with an inlet chamber and an outlet chamber co-operating with ports in the casing arranged so that fluid can be directed from the inlet chamber to the outlet chamber through alternative external paths. In the form shown in the Figures the valve member 35 is supported by needle bearings 37 and is held against axial movement by ball bearings mounted between a headed stud 38 secured to the closed end 36 of the valve member and a plate 31 clamped to the end of the valve casing by a detachable cap 26. Rotation of the valve is limited by a stop pin 44 screwed into the end 36 co-operating with stops 45, 46 riveted to the plate 31. The valve is actuated by a bi-metallic helix secured at one end to a sleeve slidably but non-rotatably engaging the valve member and at the other to a plate 34 held in the desired angular position by a pin 47 engaging one of a series of peripheral notches and clamped to the end of the casing by a detachable outlet' connection 33. The inlet chamber 49 is separated from the outlet chamber by a partition 51 fitted with a spring-loaded relief valve 54. The valve is particularly suitable for use with the oil cooler shown in Fig. 1. This comprises a core 11 divided into sections by hollow baffles 14 with staggered ports 15, and disposed within a doublewall shell 12. The space between the walls is divided into two chambers 19, 20 connected to ports 21, 22 in a valve supporting fitting 16. The outer space is bridged by an extension on the fitting 16 provided with an outlet passage 25. When the circulating oil is cold the valve is in the position shown in Figs. 3, 4 in which oil entering at 56 passes through ports 66 in the valve member and port 58 to a byepass chamber from which it passes through ports 59, 69 to the outlet chamber and thence through the outlet connection 33. As the oil warms up the connection through the byepass is gradually closed and connections between the inlet 56 and an intermediate outlet 60 and between an intermediate inlet 62 and the outlet chamber are gradually established. The passage 60 is coupled to the port 21 and the passage 62 to the port 22 so that more and more oil is passed through the hollow baffles and the jacket to thaw out the sections 11. Further heating of the oil causes the valve to rotate so as gradually to reduce the now through the baffles and gradually increase the flow through the sections 11 to the passage 25 and thence to the main outlet.

Abstract: 566,819. Air intakes for aero-engines. BLACKBURN AIRCRAFT, Ltd., and TOPLIS, J. G. May 18, 1943, No. 7887. [Class 4] An air intake system for aircraft engines comprises two or more filters arranged in echelon towards the rear with the rear edge of a forward filter connected by a plate to the front edge of the adjacent rearward filter, whereby when the normal front air intake is closed, air entering a sheltered intake at the rear is distributed over the several filters. Adequate filtering with the restricted space available is thus provided. Fig. 1 shows a wing formed with a chamber in which filters 6, 7 connected by a plate 8 are arranged and into which opens forward and sheltered air intakes 1, 3 and a lateral duct 4 leading to the engine. When the intake 1 is closed by a butterfly valve 5, air enters the intake 3 and is distributed over the filters as shown. The plate 8 may have an extension 8a at the rear edge of the filter 7 of tapered form to assist the air distribution. When the valve 5 is open, part of the air flows out of the intake 3 and thus assists the cleaning of the filters. The filters are secured to side, front and end walls which with the fairing 9 are removable as a unit. Arrangements for a fuselage having an engine in the nose and for an engine nacelle are also shown, the intakes 1, 3 being arranged above the fuselage and below the nacelle and being connected by a fairing which is removable with the filters. These filters are shown in the nacelle arrangement. The filters may be arranged side by side instead of above one another, as when the air intakes are arranged in the side of a fuselage or nacelle.

For low temperature baking control knob 40 is set between the low and off positions to open contact C1a permanently and close contacts S3 permamently and the door 25 is closed to open contacts S2 permanently so that heating elements El and E2 are connected in series with a thermostat Sl between line and neutral 1 and 2. The thermostat S1 cuts off the current supply should the temperature in the oven rise sufficiently to cause excessive temperature of door 25. For grilling, knob 40 is set to its high position, closing contacts C1a permanently or between the high and low settings in which position contacts C1a cycle on and off under the control of a bimetallic heater R1. In this position of knob 40 contacts S3 are permanently open. The door 25 is open for grilling so that its contacts S2 are closed to shunt thermostat Sl. Thus only heating element El is energized, it being under the control of cycling contacts C1a. For spit roasting the door 25 may be maintained partly closed by a spring detent device 45, 46, the door contacts S2 being held closed in this position. Heating element El is mounted at the top of the oven for radiant heating and heating element E2 is mounted at the bottom and/or around the sides of the oven to provide convective heating. The door comprises two panels of boro-silicate glass. Should the door be inadvertently closed whilst the grilling heater El is selected, contacts S2 controlled by the door will be opened so that the thermostat S1 will over-ride cycling contacts C1a and prevent overheating.
