Abstract: A high pressure fuel injection pump includes: a casing; a pump body arranged in the casing, the pump body having a piston and a sleeve reciprocating the piston therein; and a high pressure damper arranged in the casing and communicating with a discharge passage side of the pump body. The pump body and the high pressure damper are coaxially arranged in the casing.

Abstract: A high-pressure fuel supply pump with high performance is capable of securely preventing a cylinder section from seizing up and also permits improved sealing performance to minimize the chance of fuel leakage. The high-pressure fuel supply pump has: a casing (48) having a cylindrical cavity (48a); a sleeve (40) which has a cylinder section (40a) and a fixing section (40c), one end thereof closer to the fixing section (40c) being abutted against the bottom of the cavity (48a); and a piston (53) which is disposed in the cylinder section (40a). The high-pressure fuel supply pump takes in fuel through an intake passage (36) by the reciprocation of the piston (53) into a fuel pressurizing chamber (52) to pressurize it, then discharges the pressurized fuel through a discharge passage (37) to forcibly feed it into a fuel injector of a cylinder injection engine.

Abstract: A variable-discharge high pressure pump capable of facilitating the manufacturing and providing sufficient lubrication. The pump comprises a cam shaft provided with a cam surface by which a tappet displaces in accordance with the cam surface, a plunger connected to the tappet to reciprocate in accordance with the reciprocation of the tappet and accommodated in a cylindrical cylinder. Also included are a cylinder head having a contact surface brought into contact with one end surface of the cylinder. The cylinder head has a small-diameter recess portion made in the contact surface to be coupled to the cylinder and constitutes a pump chamber in conjunction with a head portion of the plunger.

Abstract: A starter in which a flange member is mounted to the starter body in accordance with the mounting conditions of the engine. An output shaft is disposed coaxially with the rotating shaft of the motor, and a front housing of the overhang type is used. Changing the mounting angle does not change the position of the motor, so that by simply replacing the flange member, a common front housing can be used to allow mounting in accordance with a larger number of mounting conditions. In addition, the tabular shape of the flange member allows die costs to be reduced.

Abstract: A starter device having a reduced output shaft diameter is provided. A stopper mechanism for impeding the outward movement of the pinion (12) along the output shaft (3a) is implemented by forming the helical splines (31) on the output shaft (3a) as being alternately open (31a, 31b) and closed (32a) helical splines. The thrust washer (21), for bearing the outward axial force of the output shaft (3a), is disposed in the front bracket (5) of the starter in front of the front bearing (16) and opposed to the front end (3d) of the output shaft (3a). Both the stopper mechanism and thrust washer configuration according to the invention allow for a reduced diameter of the output shaft (3a). The reduced diameter of the output shaft, in turn, affords the option of making the pinion (12) smaller in diameter.

Abstract: A moving contact assembly to which a moving contact is fitted so as to allow a normally open common fixed contact part to elude the moving contact and axially pass through is mounted detachably on a fixed core. A contact mold having a normally closed fixed contact part and a cap switch provided with a normally open fixed contact part, a normally closed common fixed contact part, and a normally open common fixed contact part are made axially separable. The contact mold is turned 90 degrees in one direction to allow the normally open common fixed contact part to elude the moving contact and axially pass through. Thus, when the contact mold is turned 90 degrees in the other direction to the contact mold's former condition, the moving contact can be positioned within a recessed groove of a common fixed contact.

Abstract: Irregularities on the face of the pulley groove of the pulley for driving the rotor shaft of the generator through the one-way clutch are positively extended and a frictional force between the face and the belt is increased, so that a higher torque than the drag torque can be transmitted to the one-way clutch without causing a slippage of the belt. Since no slippage occurs on the belt, the belt life can be extended. Since the one way clutch is positively operated, the inertial energy of the rotor can be effectively recovered.

Abstract: A one way clutch which permits the contact surfaces 20a of the chucks 20 of a chucking jig for chucking a clutch outer 12 to be easily machined, and the clutch outer has a plurality of taper-shaped cutouts 1a and arc-shaped support surfaces 12a serving as machining reference surfaces, each defined on the inner periphery of the clutch outer. Since the clutch outer is produced by being machined using the support surfaces as a machining reference, the contact surfaces of chucks can be easily machined.

Abstract: A vehicular charging generator provided with a one-way clutch having a clutch inner installed to a shaft of a rotor and a clutch outer interposed between the clutch inner and a pulley driven by a power unit for driving a vehicle and transmitting a power only in one rotational direction from the pulley to the shaft, wherein a male screw is formed on the shaft, a female screw is formed on an inner peripheral portion of the clutch inner and the female screw is engaged with the male screw thereby fixing the clutch inner to the shaft.

Abstract: A direct-current motor is provided with a field pole including a main magnetic pole having an axial length of Lm and an auxiliary magnetic pole; and an armature core which is rotatably supported opposite to the inner peripheral side of the main magnetic pole and rotated by the excitation force of the field pole and has an axial length of Lc. The direct-current motor which satisfies the relation of Lm>Lc is such that the corner portions of the main magnetic pole are formed so that the relation between the axial length Ln of the straight section of the main magnetic pole and Lc satisfies 1.15 Lc>Ln.gtoreq.Lc. Therefore, a direct-current motor can be made more lightweight without changing its output characteristics by cutting down the corner portions of the main magnetic pole.

Abstract: A starter has an output shaft 3a, an overrunning clutch 4 and a pinion 12 carried on the output shaft, a stopper 21 carried on the output shaft at the front of the pinion to restrict the displacement of the overrunning clutch and the pinion, and a front bearing 16 for supporting the front end of the output shaft. The stopper is formed in a cylindrical shape and is supported by an inner peripheral portion of the front bearing, and a ring 22 for fixing the stopper is fitted into a groove 23a which is formed in the output shaft at the front of the front bearing.

Abstract: An electromagnetic switch for a starter motor has a movable contact and a pair of fixed contact which are brought into contact with each other by the sliding movement of a plunger in an exciting coil; a B-terminal bolt formed integrally with one of the fixed contact, and a connecting terminal having an end surrounded by a surrounding insulation body and the other end functioning as a contacting seat portion which is fitted to the B-terminal bolt, said connecting terminal being extended in the radial direction and at a predetermined angle with respect to the insulating cap, wherein the outer configuration of the contacting seat portion of the connecting terminal is circular or a polygonal having an obtuse angle; the contacting seat of the surrounding insulation body is embedded in a resin-molded body except for its front and rear contacting surfaces; and the connecting seat portion has at its outer circumferential portion turn-prohibiting projections which are in contact with a side surface of a projection for

In the device, each of the brush holding member has a bottom portion which is provided integrally with the outer frame. Further, the first support member and the second support member are provided integrally with the outer frame.
