Title: Fuel flow control device for the idling system of a carburettor
IPC: F02M7/00
Filed: 1976-08-27
Abstract: The fuel flow control device is screwed in the tapped hole (3) of the carburettor (4) for the idling nozzle. A fuel line (20) connects the carburettor float housing to the tapped hole (3). In addition a vacuum line (21) is arranged between the carburation chamber and the fuel-air mixture inlet of the engine. The device has a closing body (17) movable in a chamber between two valve seats (8, 12), the actuating means (25) of which body are designed in such a way that when the engine is idling none of the valve seats (8, 12) is closed and that the first of the valve seats is closed at increased engine speed when the carburettor valve flap (23) is opened, whilst the closing body (17) rests on the second valve seat (12) when the engine speed is reduced due to sudden closure of the carburettor valve flap (23). Due to the fact that the full quantity of fuel can flow to the engine by way of an orifice (9) only when idling and the flow is interrupted or reduced in the case of a high or suddenly reduced speed, the fuel consumption can be reduced and combustion conditions improved. <IMAGE>

Title: Hydraulic system especially for motor vehicles
IPC: F15B1/027
Filed: 1959-10-23
Abstract: 875,606. Hydraulic intensifiers. FORD MOTOR CO. Ltd. Oct. 23,1959 [Oct. 23, 1958], No. 35992/59. Class 69 (2). An hydraulic system for a motor vehicle comprises a source of fluid pressure connected to the inlet 35 of an intensifier having means for diverting a portion of the fluid flowing from the inlet to at least one non-amplified fluid outlet 36, and means 24 operable to amplify the diverted portion of the fluid for discharge through an amplified fluid outlet 37, the diversion of fluid occurring after utilization of the fluid to operate the pressure amplifying means. The non-amplified fluid outlet 36 may be connected to the power steering system of the vehicle, and the amplified fluid outlet 37 to a line connected to an accumulator and, for example, power-operated brakes. The amplifying means consists of a piston 24 having large and small ends 32, 34 reciprocable in cylinders 28, 31, respectively. The piston is reciprocated by fluid pressure from the inlet acting on opposite faces 51, 52 thereof under the control of a reversing valve 25 which is urged to one position by a spring 38 to disconnect the face 52 from the supply and move the piston in one direction, and is moved to another position by fluid pressure acting in a chamber 49 to connect the face 52 to the supply to move the piston in the opposite direction, the supply to the chamber 49 being controlled by the opening and closing of passages 39, 41, 42 in the piston during its movement. During its movement to the right, and to the left because of passages 54, 61, the piston displaces fluid in a chamber 29, part of the fluid passing through a passage 45 to the non-amplified fluid outlet 36, and part passing through a passage 57 and non- return valve 26 into the cylinder 31. During movement to the left, a packing 63 on the small diameter piston 34 pressurizes fluid in a chamber 31a which is connected by a passage 58 to the amplified fluid outlet 37, and during movement to the right, fluid is pressurized in the cylinder 31 which is also connected to the amplified fluid outlet 37 by a passage 62, non-return valve 27, the chamber 31a and the passage 58. The dimensions of the pistons and cylinders are such that with a constant delivery pump connected to the inlet 35, the pressure at the outlet 37 is the same for both directions of movement of the pistons. A by-pass valve 65 is connected to the inlet 35 and amplified fluid outlet 37 and is arranged to open when the accumulator is charged to a predetermined value, the fluid then by-passing the intensifier pistons and passing directly through passages 71 and 76 to the non-amplified outlet 36. Specification 875,607 is referred to.

Filed: 1967-08-09
Abstract: 1,181,525. Winding webs. NISHIMURA SEISAKUSHO CO. Ltd. 9 Aug., 1967 [13 Aug., 1966], No. 36539/67. Heading B8R. A web-winding system comprises a supply roll, delivery means in the form of a feed roller between the supply roll and a take-up roll, and differential transmission means for imparting differential outputs from a single drive power source to the delivery roller and the take-up roll, the differential transmission means also including therein a speed change mechanism. The increase in diameter of a web wound on to a spindle driven web-roll 21 via idler rollers 57, 58, feed rollers 59, R1, 62 and longitudinal slitters 60, 61, is detected by a roller 63 pivoted at 67. Movement of the roller 6 adjusts a servovalve 68, which controls an hydraulic motor (MIII, Fig. 11, not shown), driving screw-jacks (71) to lower the web-roll 21. With the lowering of the web-roll 21, an assembly (56), consisting of an hydraulic motor (MII), and transmission means (51, 52, 53), is also lowered. This causes the capacity of the hydraulic motor (MII) to be automatically increased by means of a camplate (64), so that the output torque is increased and the r.p.m. decreased. A decrease in the speed of motor (MIT) will result in an increase of the speed of an hydraulic motor MI driving feed-roller R1, since both motors are supplied with hydraulic fluid from a pump (P). The speed of the web may be kept constant by utilizing a variable capacity pump (P) or variable speed motor (M) to drive the pump (P). A signal from a speed detector is compared with a reference signal to control the pump or the motor which ever is appropriate. (Figs. 14 and 15) illustrate suitable hydraulic transmission systems, and (Fig. 16) illustrates a mechanical drive transmission system utilizing an eddy current coupling speed-change mechanism.
