摘要： A fuel injection system for a hydro carbon engine is provided with a simplified electronic governor system for controlling the maximum speed of the engine. The governor system is operatively associated with an electronic control unit (ECU) for operating the engine. A pulse width modulated fuel valve is provided with a pressure intensifier device enabling the fuel system to use low pressure signals in providing a fuel supply to the engine. The fuel system further is provided with a throttle body having the ECU, the fuel valve and the governor system integrated with on another in a single package for mounting on the engine.

摘要： In at least some implementations, a carburetor has a metering system that controls fuel flow from a fuel source to an air-fuel passage. The metering system includes a metering diaphragm sealed to a body of the carburetor to at least partly define a metering chamber between the metering diaphragm and the body, and the metering diaphragm has a continuous layer and a discontinuous layer. The continuous layer is responsive to fluid pressure within the metering chamber and moves against the discontinuous layer to open a metering valve to allow fuel flow from the fuel source and into the metering chamber when said fluid pressure is below a reference pressure.

摘要： An automatic residual fuel vent device for a carburetor, the device including a fuel supply passage (15) connecting a fuel tank (TF) and a float chamber (10), a negative pressure passage (17) connecting an intake passage (8) and a negative pressure operating chamber (53) of a diaphragm pump (PD), a fuel vent passage (16) connecting the float chamber (10) and the fuel tank (TF), a single changeover cock (CO) provided so as to straddle the fuel supply passage (16) and the negative pressure passage (17), a negative pressure surge tank (TS) provided in the negative pressure passage (17), and the diaphragm pump (PD), which is connected to the fuel vent passage (16) and is operated by negative pressure of the negative pressure surge tank (TS), residual fuel of the float chamber (10) being returned to the fuel tank (TF) by the diaphragm pump (PD) operated by negative pressure from the negative pressure surge tank (TS) in accordance with the changing over of the changeover cock (CO). This enables residual fuel within the float chamber of the carburetor to be reliably returned to the fuel tank by intake negative pressure accumulated in the negative pressure surge tank and, furthermore, residual fuel can be vented by the changing over of a single changeover cock, thus enabling the number of components to be reduced and the device to be provided at a low cost.

摘要： An O-ring shaped annular rib 63 is disposed around the outer periphery of a flexible diaphragm member 62, and grooves 70 and 71 are formed for receiving the annular rib 63 in the hollow space in the compressed state wherein the foregoing hollow space is defined between a first synthetic resin member 60 for holding the diaphragm 62 in the clamped state and a second synthetic resin member 61. While the annular rib 63 is received in each of the grooves 70 and 71, a location 64 where the first synthetic resin member 60 and the second synthetic resin member 61 come in contact with each other at the positions located outward of the grooves 70 and 71 is subjected to welding with the aid of a supersonic welding tool 65.
A gap 76 is formed between the first synthetic resin member 60 and the supersonic welding tool 65, and this gap 76 is caused to disappear by progressively performing a welding operation. At this time, further proceeding of the welding operation is inhibitively suppressed by allowing the first synthetic resin member 60 and the supersonic welding tool 65 to come in contact with each other, and the compression rate specified for the annular rib 63 is kept constant. Alternatively, a metallic spacer 77 is interposed between the first synthetic resin member 60 and the second synthetic resin member 61. In this case, a gap 78 is formed in the hollow space defined by the second synthetic resin member 61 and the metallic spacer 77 prior to a welding operation, and this gap 78 is caused to disappear as the welding operation is progressively performed so as to allow further proceeding of the welding operation to be inhibitively suppressed. At this time, the compression rate specified for the annular rib 63 is kept constant.

摘要： Two-stage volumetric pump for pumping liquefied petroleum gases in the liquid phase, which pump is of the type consisting of: two chambers (110, 210); a valve (120), communicating with the first chamber, for the admission of liquefied petroleum gas, to be pumped in the liquid phase; a valve (220), communicating with the second chamber, for the delivery of the pumped liquid; a transfer duct (310) uniting the two chambers and fitted with a valve (320) preventing the return of liquid from the second chamber to the first. According to the invention, each chamber comprises a wall formed by a diaphragm (130, 230) freely deformable in such direction as to increase the volume of the chamber under the effect of the pressure of the liquid, and operably deformable in the opposite direction under the action of actuating means acting alternately on the diaphragms of both chambers.
