Title: Improvements in or relating to a Device for Regulating the Flow of Fuel Injected into an Internal Combustion Engine.
IPC: F02M59/30
Filed: 1968-10-15
Abstract: 1,186,135. Regulating I.C. engines, fuel injection pumps. AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT. Oct.15, 1968 [Dec.20, 1967], No.48855/68. Headings F1A and F1B. The invention relates to a device for regulating the flow of fuel injected into an internal combustion engine, the device comprising a rolling membrane one side of which is subjected to pressure in the engine admission pipe while the other side of the membrane is connected to a chamber which communicates through a first orifice with atmosphere and through a second orifice with the engine admission pipe, at least one of the orifices being of variable area and being controlled in dependence on atmospheric pressure. The device comprises a casing 1 formed in two parts 1a, 1b, the part 1a being formed with a flange 16 in which slides the rod 20 of a piston 22, a rolling membrane 3 being secured to the piston and being clamped between the casing parts 1a, 1b so as to define two chambers 17 and 4. The lower end of the rod 20 carries two balls 31, 32, the ball 32 engaging the rectilinear surface 33 of the casing and the ball 31 engaging the cam surface 30 of a lever 27 pivotally mounted at 29. The lever forms an abutment for the fuel pump plunger 24 which is acted on by push rod 25 which in turn is driven by the rotary cam 26. Thus the axial position of the piston 22 controls the angular position of the pivoted lever 27 which in turn controls the amount of fuel delivered to the engine. The chamber 17 below the membrane 3 is connected by line 18 to point 19 of the air admission pipe 11 downstream of the throttle valve 12. The chamber 4 above the membrane 3 is connected by line 5 to a chamber 6. The chamber 6 is in turn connected through a variable orifice 7 to atmosphere and through a fixed orifice 8 and line 9 to a point 10 of the air admission pipe 11 downstream of the throttle valve 12. The valve orifice 7 is controlled by a needle valve 13 in dependence on atmospheric pressure, the needle valve being connected to an aneroid capsule 14 whereby the crosssection of the orifice 7 increases upon decrease of atmospheric pressure. In Fig.3 (not shown), it is arranged that the orifice by which the chamber 6 communicates with atmosphere increases upon decrease of atmospheric pressure. In Fig.4 the orifice 7 by which the chamber 6 communicates with atmosphere is fixed while the orifice 8a by which the chamber communicates through line 9 with the admission pipe 11 varies in dependence on atmosphere pressure, the slide 38a in which the orifice 8a is formed being connected to the movable end wall of the aneroid capsule 14. In Fig.5 (not shown), both orifices of the chamber 6 are variable in dependence on atmospheric pressure. The theory of the invention is described in detail.

Abstract: 1366090 Air conditioning FLUIDTECH CORP 20 Oct 1971 48859/71 Heading F4V An air conditioning system in which the supply of conditioned air to a room is controlled by a bi-stable fluidic oscillator, comprises an inlet channel 10 a control chamber 13 and two outlet channels 11a, 11b. A pair of Pitot tubes 17a, 17b are mounted in the outlet channels 11a, leading to the room to be conditioned and 11b leading to the return duct of the system. Assuming air is flowing in outlet channel 11b, the tube 17b is connected to one of the control channels 16a of a second bi-stable fluidic device and to a vent valve 18b which is controlled by a thermostatic device 18c mounted in the room. As shown, this valve is closed, therefore all the air from Pitot tube 17b flows into channel 16a and causes the direction of the air stream from channel 14 to be switched from channel 15a to 15b, thereby directing this air stream to channel 12b against the side of the main stream flowing through chamber 13. This causes the main stream to switch its flow to outlet channel 11a and pass into the room. Pitot tube 17a then acts in a similar fashion to switch the flow of air to channel 11b. The thermostat controls the vent valves 18a, 18b and thereby determines the proportion of the oscillation period during which air flows to the room. Various positions of the thermostat 18c and other embodiments are also disclosed.

Abstract: 1482082 Shoe and lasting machines BRITISH UNITED SHOE MACHINERY CO 21 Oct 1974 [20 Oct 1973 5 June 1974] 48991/73 and 24866/74 Heading A3B A shoe upper conforming lasting machine has a pair of gauges arranged on opposite sides of a shoe assembly and operated sequentially to engage the shoe and position it correctly within the machine. In one form, the shoe assembly is mounted upon a pin 10, Fig. 1, between gauges or pads 508, 509 (see also Fig. 2). Pneumatic servos 522, 523 are operated one after the other, depending upon whether the shoe is for a left or right foot, to pivot the pads 508, 509 upwards about pins 514 and into engagement with the forward sides of the shoe assembly. One servo, e.g. the servo 523, is fed with high pressure air, to raise its pad 509 to the vertical position, and the other servo 522 with low pressure air, so that its pad 508 engages the shoe assembly, gently pushes it against the pad 509, and thus correctly aligns the shoe &c axis. Selection of which servo 522, 523 is operated first is manual. When the shoe assembly has been aligned as described, a toe-engaging plate 68 on a servo actuated lever 52 and a toe pad 72 engage the shoe assembly, and the gauges or pads 508, 509 are withdrawn so as not to impede subsequent wiping operations. In a modified form in which selection of the sequence of operation of the pad servos 522, 523 is automatic instead of manual, a sensor finger 620, Fig. 3, pivoted on a pin 622 by a servo 626 and carried on the lever 52 actuates a control valve or switch 634. The servo 626 is actuated to swing the sensor finger 620 perpendicular to the main axis of the shoe assembly, &c. The machine is set to operate on a right-hand shoe, in which case the servo 522 is supplied with high pressure air, the servo 523 with low pressure air, and the finger 620 pivots in to the end of its stroke without contacting the shoe assembly, &c. If, however, a left-hand shoe, &c is being lasted, the sensor finger 620 engages the shoe, &c, and the switch device 634 changes the control circuit to supply low, instead of high, pressure air to the servo 522 and high, instead of low, pressure air to the servo 523.
