PROBLEM TO BE SOLVED: To prevent a valve means of a fuel injector from damage or blockage by particulate material originating internally of the fuel injector. SOLUTION: The fuel injector has a filter 30 provided within a tip portion 12 of an injector body 10, downstream of a fuel inlet port 24 and upstream of a spray aperture 14. The filter 30 is in the form of a hollow truncated cone with a base region having an outer diameter dimensioned to be a press fit against inner sides of the tip portion 12 such that the filter is a press fit within the tip portion. A top or upper region of the cone terminates in an aperture through which a pintle 16 passes, and the aperture has an inner diameter dimensioned to be a close sliding fit over the pintle 16.

PROBLEM TO BE SOLVED: To provide a pressure measurement device preventing biological pollution and requiring no calibration between respective operations. SOLUTION: This device 10 for performing immersion measurement of fluid pressure is provided with a disposable housing 12 having a fluid contact area 14 and a fluid noncontact area 16. A disposable diaphragm 18 in a nonelastic condition substantially is arranged inside the housing for separating the fluid contact area 14 from the fluid noncontact area 16. One side face 17 of the diaphragm 18 is brought into contact with fluid, and the diaphragm is provided with flexibility sufficient for moving by a predetermined distance in the axial direction within the fluid noncontact area in response to contact with the fluid. The predetermined distance is substantially proportional to the fluid pressure. An electronic detector 22 is attached movably in the housing 12 adjacently to the fluid noncontact area 16 and separated from the diaphragm 18. The electronic detector can determine the fluid pressure. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an advance arrangement capable of timing adjustment without affecting light load control spring pre-load. SOLUTION: An advance arrangement comprises an advance piston 12 slidable within a first bore 14, a servo piston 24 slidable in the piston 12 responsive to speed dependent fuel pressure variations within a servo control chamber 37, and a light load piston 26 moveable relative to the piston 12 in response to fuel pressure variations, wherein the light load piston 26 is arranged in a cold cranking sleeve 120 which is slidable in the first bore 14 against the action of a cold cranking control spring 128 in response to fuel pressure variations within a cold cranking control chamber 134 such that the spring 128 acts to slide the sleeve 120 a predetermined distance in the advance direction and fuel pressure variations within the control chamber 134 serves to slide the sleeve 120 back in the retard direction.

PROBLEM TO BE SOLVED: To provide a vane cam shaft phase shifter having improved reliability on pin locking operation, thus improving the fuel consumption of an internal combustion engine. SOLUTION: The vane cam shaft phase shifter 200 having a 40° crank angle before TDC and a 30° crank angle after TDC comprises a stator seat 136 formed at a rotation position in a middle between a full angle of lead and a full angle of delay. The locking pin 126 in a vane 116 of a rotor 112 is engaged with the seat 136 to lock the rotor at the middle position. The pin is disengaged therefrom by pressure engine oil, independently of an oil flow for the angles of lead and delay of the rotor. The seat and the end of the locking pin are discharged through passages in the rotor and the stator 137. These passages are aligned when the rotor is at a selected locking angle. To position the locking pin over the seat, a phase adjusting speed is reduced for gaining a sufficient time to engage the locking pin with the seat. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an injection nozzle for an internal combustion engine, having improved energy efficiency. SOLUTION: A valve needle 16 engages with a valve seat 18 formed by a bore 14 for controlling the supply of fuel passing through an injection nozzle outlet 20. It has a first valve region 28, a second valve region 30, and a seat region 38 where the nozzle abuts on the valve seat in the non-injection state. The valve needle 16 also has a diffusion space portion 36 into which the fuel passing through the vale seat flows in the non-injection state, as well as a diffusion region 40 in a partially rotation elliptical shape or a partially spherical shape where a smooth transition portion is formed for a branch fuel flow into the diffusion space portion 36.

PROBLEM TO BE SOLVED: To provide a variable orifice nozzle type injection nozzle operating for reducing or eliminating the problem of a load in the horizontal direction. SOLUTION: This injection nozzle 4 for an internal combustion engine has a nozzle body 6 defining a seat surface 28 and having a first nozzle outlet 12, and an outside valve member 10 stored in the nozzle body 6 and engageable with an outside seat 32 defined by the seat surface 28 so as to control fuel injection passing through the first nozzle outlet 12. A hole 52 having an inside hole surface is arranged in the outside valve member 10, and insert members 50a and b are stored in the hole 52. The insert members 50a and b have a partial spherical head 50a arranged in an inner diameter of the hole 52 so as to define annular clearance 55 to the inside hole surface. The outside valve member 10 can engage with an inside seat 56 defined by a surface of the partial spherical head 50a so as to control a fuel flow turning to the first nozzle outlet 12 by passing through the annular clearance 55.

PROBLEM TO BE SOLVED: To provide an electric connector which can eliminate influence on deformation of a spring contact terminal by giving a double contact function. SOLUTION: The electric connector is provided with an electric conductive main part in which a spring contact terminal having at least one double contact function is equipped. Each spring contact terminal of the double contact function has an arm which arises from a first nose of the electric conductive main part and the arm is bent 180° to form an arm part at a top. A first spring is connected with the arm part at the tip and connected with a contact part of the arm. A second nose is connected with the contact part, where the arm is bent by 180°. A second spring is connected with the second nose and the second spring supports the arm end which contacts at the electric conductive main part, preferably, at a point of a relief spring. The first spring and the second spring function independently so that resilience arrangement of each contact part can be brought about mutually. COPYRIGHT: (C)2007,JPO&INPIT
