Abstract: The plunger pump according to the present invention discharges fuel by reciprocation of a plunger, and comprises metallic diaphragm type dampers, provided at a fuel inlet side and a fuel outlet side, respectively, for reducing pressure pulsation of fuel. Each metallic diaphragm type damper comprises a pressure chamber for receiving fuel pressure, a back pressure chamber into which gas is charged, and a metallic diaphragm for defining the pressure chamber and the back pressure chamber. Since the metallic diaphragm type dampers are provided at the fuel inlet side and the fuel outlet side, respectively, noise and vibration caused by pressure pulsation are reduced at the fuel inlet side and the fuel outlet side. Also, since the diaphragms are metallic diaphragms, deterioration thereof generated by fuel liquid and back pressure gas is low, reliability is high, and the lifetime is long.
Abstract translation: 根据本发明的柱塞泵通过柱塞的往复运动来排出燃料，并且分别包括设置在燃料入口侧和燃料出口侧的金属隔膜式阻尼器，用于减少燃料的压力脉动。 每个金属隔膜式阻尼器包括用于接收燃料压力的压力室，用于充气的背压室和用于限定压力室和背压室的金属隔膜。 由于金属隔膜式阻尼器分别设置在燃料入口侧和燃料出口侧，所以在燃料入口侧和燃料出口侧分别导致由压力脉动引起的噪声和振动。 此外，由于隔膜是金属隔膜，因此燃料液和背压气体产生的劣化低，可靠性高，寿命长。

Abstract: An electromagnetic pump having an electromagnet carried by the housing external to the fluid chambers, and an armature moveable in the housing having a pole magnetically attracted by the electromagnet and a piston to force fluid out of the chambers and through the pump outlet. A path provides controlled bypass for bubbles in the fluid around the armature piston between the fluid pumping chamber and the fluid receiving chamber only during the return stroke of the armature. Fluid inertia is reduced by an outlet orifice in the path of fluid flow from the pump outlet and by a bypass orifice for fluid flow in the bypass path, the orifices being provided either individually or in combination depending upon the fluid flow characteristics of the system including the pump. An accumulator in the fluid flow path between the pump outlet and a catheter leading away from the pump alleviates inertial and viscous effects arising from the catheter. The armature pole has a fluid-contacting section of material which is compatible with and corrosion resistant to the fluid, which can be a body of magnetic material within a titanium enclosure or a body of chrome-molybdenum-iron alloy.

Abstract: An electromagnetic pump comprising a housing having fluid receiving and pumping chambers in communication with an inlet and outlet, respectively, an electromagnet carried by the housing external to the fluid chambers thereof, and an armature movable in the housing having a pole portion magnetically attracted by the electromagnet and a piston portion to force fluid out of the chambers and through the pump outlet. A path provides controlled bypass for bubbles in the fluid around the armature piston portion between the fluid pumping chamber and the fluid receiving chamber only during the return stroke of the armature. Fluid inertia is reduced by an outlet orifice in the path of fluid flow from the pump outlet and by a bypass orifice for fluid flow in the bypass path, the orifices being provided either individually or in combination depending upon the fluid flow characteristics of the system including the pump. An accumulator in the fluid flow path between the pump outlet and a catheter leading away from the pump alleviates inertial and viscous effects arising from the catheter. The armature pole portion has a fluid-contacting section of material which is compatible with and corrosion resistant to the fluid, which can be a body of magnetic material within a titanium enclosure or a body of chrome-molybdenum-iron alloy. The check valve and inlet are so arranged that the pump displacement can be reduced without reducing the bubble pumping capability of the pump.

Abstract: The combustion chamber structure having a combustion chamber almost at the center of the piston is installed in a cavity formed in the piston body with a heat insulating layer interposed therebetween. The combustion chamber structure and the piston body are joined by a joining member. The combustion chamber structure is formed with a nozzle insertion hole and communication holes. The joining member is made of a material with a thermal expansion coefficient intermediate between those of the piston body and the combustion chamber structure, or of almost the same kind of material as the piston body. Alternatively, the combustion chamber structure forms a piston head portion and the piston body forms a piston skirt portion. The lower surface of the piston head portion is formed as a tapered surface that is inclined toward the periphery. The upper surface of the piston skirt portion is also formed as a tapered surface that extends along the opposing tapered surface of the piston head portion. The lower surface of the outer periphery of the piston head portion and the upper surface of the outer periphery of the piston skirt portion are in firm contact with each other. The combustion chamber structure of this invention is so constructed that a rich air-fuel mixture is generated in the upper part of the combustion chamber and that the mixture is quickly ejected into the cylinder chamber to reduce the combustion period.

Abstract: A fuel pump for a vehicle includes a brushless motor for operating this fuel pump, and a control circuit for the brushless motor is contained in the fuel pump. Difficulties such as a cutting of the wiring due to an electrolytic corrosion of electrically-conductive portions, and a short-circuiting thereof, are prevented. A pump portion, a motor portion and a discharge portion are provided in a housing of the fuel pump. The motor portion includes a rotor and a stator portion. The stator portion is molded by a resin material into a cylindrical shape with a closed bottom. The stator portion supports a shaft of the rotor. Stator coils are molded in a peripheral wall portion of the stator portion, and a container containing the control circuit is molded in the bottom wall portion of the stator portion. The stator coils, copper wires extending therefrom, and terminals from the control circuit are completely molded in the above resin material. With this arrangement, the stator coils, the control circuit, and the electrically-conductive portions extending between the control circuit and the stator coils are not exposed to the fuel at all, and therefore the above difficulties are prevented.
