摘要： A needle is forced to open an injection hole by reducing a pressure of fuel in an injection control chamber to thereby inject fuel stored in a fuel storage, while the needle is forced to close the injection hole by increasing the pressure of fuel in the injection control chamber to thereby terminate injection of fuel from the injection hole. In a valve-closing stroke of the needle to close the injection hole, fuel pressure is supplied from a common accumulator to the fuel storage and the injection control chamber in such a manner that the pressure to supply fuel to the fuel storage is lower than that to supply fuel to the injection control chamber. In this way, a force acting on the needle toward the injection hole side can be increased in the valve-closing stroke, to thereby accelerate a valve-closing speed of the needle.

摘要： A distributor type fuel injection pump which includes a relief passage having one end thereof opening in the pump working chamber and the other end communicating with a zone under a lower pressure. Said relief passage is so arranged as to be permanently kept closed by a valve means which is actuated by a valve actuating means for actuating said valve means in response to a fuel supply pressure varying as a function of the engine rotational speed, except in a predetermined low engine speed range, to obtain a decreased injection rate during idling so as to increase the injection period. Thus, the rate of combustion of the engine is reduced to minimize the combustion noise.

摘要： A fuel injection pump for internal combustion engines for controlling the fuel quantity with an electric closed-loop control device, which controls an electric positioner, which in turn actuates an element that determines the fuel injection quantity per pump piston supply stroke. The supply of fuel to the pump work chamber is effected via a fuel supply line, in which an adjustable throttle is disposed. The throttle is actuated in accordance with the position of a gas pedal, but it controls an increasingly larger through cross section of the fuel supply line than would correspond to the fuel metering by the closed-loop control device. A minimum through cross section is defined by a fixed throttle. With this apparatus, emergency operation if the electric control system for the fuel injection quantity fails can be attained, without the apparatus for emergency operation interfering with fuel metering by the closed-loop control device. In particular, the fixed throttle prevents racing of the engine counter to the intentions of the driver in the event that the closed-loop control system fails.

摘要： A distributor type fuel injection pump which includes a port formed within the pressurized fuel distributing plunger with one end thereof communicating with the pump working chamber and the other end terminating in the outer periphery of said plunger, and a relief passage having one end thereof terminating in the inner peripheral wall of the plunger barrel and the other end communicating with a zone under a lower pressure. Said port and relief passage are so located as to register with each other at the beginning of the fuel delivery stroke of said plunger, and said relief passage is so arranged as to be permanently kept closed by a valve means which is actuated by a valve actuating means for actuating said valve means in response to a fuel supply pressure varying as a function of the engine rotational speed, except in a predetermined low engine speed range, to obtain a decreased injection rate during idling so as to increase the injection period, thereby reducing the rate of combustion of the engine to largely reduce the combustion noise.

摘要： An air flow rate sensor, located in the induction tube of an internal combustion engine, displaces a fuel metering slide, thereby changing the fuel flow and the fuel pressure gradient. This pressure gradient is applied to a differential pressure valve which actuates a fuel flow control throttle until the pressure gradient has been restored to a nominal value, corresponding to a desired fuel-air ratio.In a variant embodiment, an arbitrary change in the metered out fuel results in a fuel pressure gradient which is used to reset an air-flow control member until the nominal value of the pressure gradient has been restored, corresponding to a desired fuel-air ratio.

摘要： 893,422. Fluid-pressure servomotor-control systems. HAGAN CHEMICALS & CONTROLS Inc. July 23, 1959 [Dec. 5, 1958], No. 25343/59. Class 135. [Also in Group XVIII] The loss in weight of pickled meat products is continuously metered by a pneumatic weighing apparatus 20, Fig. 1, supporting the products on a " tree " 12 in a smokehouse, the weighing apparatus producing a pneumatic pressure proportional to the weight of the products which pressure and a reference pressure are arranged to actuate devices exerting contra-turning forces on the beam 35 of a ratio totalizer 27 which in turn develops an output pressure that operates an alarm when a predetermined weight loss has been achieved. The weighing apparatus 20 comprises a pivoted beam one end of which carries the support 19 for the meat products and the other end of which acts on a thrust block 105, Fig. 8, to which is secured a diaphragm 100 forming one wall of a pressure chamber 103. When the beam turns and raises the thrust block a valve 104 is closed and a valve 111 opened to admit pressure air into the chamber 103 from a source connected to an inlet tube 117 of the apparatus at 114. The pressure behind diaphragm 100 builds up to the value necessary to rebalance the beam, at which value both valves 104 and 111 become closed and the pressure in line 20a meters the weight of the load. The reference pressure is derived from a device 26, Fig. 1, in which a diaphragm 89 loaded on one side by a screw-adjusted spring 93 causes the pressure in a chamber 87 on the other side of the diaphragm to build up to a steady value applied to the line 26a, the pressure fluid being supplied to the chamber from a line 41, by way of a valve 97 which operates in like manner to the valve 111 of the weighing apparatus 20. In operation, the weight pressure in line 20a and the reference pressure in line 26a are converted into beam-loading forces by devices 37 and 38 respectively and as the product weight falls an increasing force is exerted on a device 40 acted on by the other end of the beam 35 and this force is converted into a pressure transmitted to line 27a, the device 40 being of like construction to the device 26 but having a beam-loaded plunger replacing the screw 94. The pressures in lines 20a and 27a act respectively on bellows 29 and 28, Fig. 2, which in turn operate pens 21, 22 in a recorder M to move towards each other as the product weight falls, contacts 42, 43 carried by the penoperating lever systems being closed to operate the alarm when a predetermined weight loss, whose value depends on the initial weight and the magnitude of the reference signal, has been achieved. In a modified system, Fig. 3, the weight signal is applied by line 20b-3 to device 38-3 and the reference signal by line 26a-3 to device 37-3 and a weight-loss signal thus produced in a device 40-3 is further amplified by a pivoted beam device 49 whose fulcrum 66 is adjustable so that the output signal in a line 57 may be made to be a pressure which increases in known proportion to the decrease in weight. In this system the initial pressure in line 57 is zero and it builds up to a value corresponding to the initial weight of the products when a predetermined percentage weight loss, dependent on the setting of fulcrum 66, has been achieved. In further modifications (Figs. 4 and 5, not shown), the output pressure of a ratio totalizer such as 27 in Fig. 1 either increases from zero to a value proportional to the desired weight loss or decreases from such a value to zero in the course of a smoking operation and the recorder M is omitted, the change of pressure between zero and the value representative of the desired loss or vice versa being made to cause directly the actuation of an alarm switch.
