摘要： There is provided a high pressure fuel pump which includes a reliable fuel seal having a long durability and which can be produced at a relatively low cost. When a rotating shaft 4 is rotated to rotate a swash plate 7, such rotation is transmitted to a piston shoe guide plate 8 through a thrust ball bearing 9. Since the plate 8 is supported by a spherical portion 16 of a rod 14 mounted to a body 12, the plate 8 performs a precession to recurrently operate a plurality of fuel pumps 21 to 25 disposed around the rod 14. Each of the fuel pumps 21 to 25 includes a bellows provided between an outer end of the piston and the body 12, and the bellows completely seals a fuel leaked from a sliding clearance between the piston and the cylinder. Since the leaked fuel is introduced into a return passage 19 through a groove formed in an outer wall of the cylinder, a large internal pressure is not applied to the bellows and therefore, the bellows can be made of a low-priced material such as Teflon.

摘要： A pump has a rotor made of synthetic resin in a fixed housing which are adjacently arranged while forming a gap between the housing and the rotor to force-feed a medium containing water moisture, in which the rotor is made of a resol-type synthetic resin so that a dimensional change rate of the rotor is 0.15% or less for a medium having a moisture content rate of 10 wt % or less, whereby a sufficient pump performance can be obtained while relatively increasing the degree of freedom of the moisture content rate of the medium to reduce the corrosiveness of the medium.

摘要： A throttle body assembly for supplying a mixture of fuel and air to an intake port of an internal combustion engine, integrally incorporating a fuel injection valve, a fuel pump, a fuel supply passage defined in the throttle body and extending from the fuel pump to the fuel injection valve, and a fuel pressure control valve directly incorporated in the throttle body to control pressure of fuel in the fuel supply passage. Thus, there is no need to use an external tubing system for supplying and returning fuel to and from the fuel injection valve, and the throttle body assemby may be simplified in structure so as to facilitate the assembling and servicing of the throttle body assembly. Further, an electronic control unit and sensors associated with the control unit are both directly mounted on the throttle body so that wiring around the throttle body may be eliminated.

摘要： A control system for a throttle valve in automotive internal combustion engines in which the throttle valve is both mechanically linked with an accelerator pedal and also connected with an actuator such as a pulse motor for fine-adjusting the opening of the throttle valve in the closing direction in accordance with the operating state of the engine after it has been opened through the mechanical linkage. A spring is inserted in the mechanical linkage system between the accelerator pedal and the throttle valve. The provision of the spring substantially isolates the accelerator pedal from forces acting in other parts of the system so that the operator does not feel an unnatural change in the amount of pressure needed to depress the accelerator pedal when the actuator goes into operation.
