Claims
- 1. A fuel pump for use in an internal combustion engine, comprising:
- a rotating shaft driven by rotation of the internal combustion engine;
- a fuel pressurizing mechanism having a plunger and a cylinder for pressurizing fuel in said fuel pressurizing mechanism;
- a movable plate for reciprocating said plunger of said pressurizing mechanism by synchronizing the rotation of the internal combustion engine in an axial direction motion component of said plate;
- the fuel is pressurized and compressed by a reciprocating movement of said plunger of said pressurizing mechanism; and
- a single impermeable flexible isolating member mounted on said movable plate to isolate the fuel in said fuel pressurizing mechanism;
- whereby the fuel is prevented from leaking from a side of said pressurizing mechanism to side of said plate by said single impermeable flexible isolating member.
- 2. A fuel pump for use in an internal combustion engine, comprising:
- a rotating shaft driven by rotation of the internal combustion engine;
- a fuel pressurizing mechanism having a plunger and a cylinder for pressurizing fuel in said fuel pressurizing mechanism;
- a spring slidably received in the cylinder so as to bias the plunger out of the cylinder;
- a rotation motion mechanism comprising a wobble plate for reciprocating said plunger of said pressurizing mechanism by synchronizing the rotation of the internal combustion engine in an axial direction motion component of said rotation motion mechanism, the fuel being pressurized and compressed by a reciprocating movement of the plunger; and
- a single impermeable flexible isolating member having one end thereof mounted at said wobble plate to isolate the fuel in said fuel pressurizing mechanism;
- whereby the fuel is prevented from leaking from a side of said pressurizing mechanism to side of said rotation motion mechanism by said single impermeable flexible isolating member.
