摘要： PROBLEM TO BE SOLVED: To evade interference to other component to facilitate mounting. SOLUTION: This solenoid valve system 1 controls a current value supplied to a coil 20 to regulate driving force by which a spool 40 is pushed along the anti-linear solenoid 10 direction by a linear solenoid 10, and regulates hydraulic pressure of a hydraulic fluid flowing out from an output port 34. The hydraulic pressure of the hydraulic fluid flowing out from the output port 34 decreases in proportion to the current value supplied to the coil 20. A relation r2>=r1 is satisfied, where r1 represents an outside diameter of solenoid driving part 10, and r2 represents an outside diameter of a cylindrical part 32 of a valve housing 31. An outside diameter of a flange part 39 of the housing 31 is equal to the outside diameter of the cylindrical part 32 or less. Since the outside diameter of the solenoid driving part 10 is equal to the outside diameter of the housing 32, the whole solenoid valve device 1 is stored, for example, in a storage hole of a same diameter formed in a body of a hydraulic controller of an automatic transmission.

摘要： PROBLEM TO BE SOLVED: To provide a valve timing adjusting device which can be machined with high accuracy by a simple structure. SOLUTION: In a shoe housing 3, a circumferential wall 4 and a front plate 5 are integrally formed by aluminum die-cast, and at the same time, distortion absorbing holes 42 are formed in respective shoes 3a, 3b, 3c. Also, a sectorial space part 40 which is partitioned by the shoes 3a, 3b, 3c and in which a vane is rotatively stored, is formed in the shoe housing 3. Arched cross sectional recessed parts 50 are axially formed in the peripheral walls of the shoes 3a, 3b, 3c, and clamp seats 51 are formed on a front plate 5 side. When the clamp seats 51 are pushed and pressed by pulling claws 52, the sides of the clamp seats 51 further peripheries from the distortion absorbing holes 42 are elastically deformed, however, the sides thereof further inner circumferentials from the distortion absorbing holes 42 are hardly deformed. Therefore, the machining accuracy of the surface to be machined of the shoe housing 3 which exerts influence on sealed properties and sliding abrasion between members, can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a valve timing adjusting device for reducing manufacturing manhours, and capable of easily changing driving torque by a hydraulic fluid. SOLUTION: A base material of a vane rotor 15 and a peripheral wall 12 of a housing member for relatively rotatably housing the vane rotor 15, is formed by cutting an extruded mold in the desired length by extrusively molding an aluminum alloy. The aluminum alloy is extracted after being extruded so that the extruded mold can be highly accurately molded. A 6000 system of Al-Mg-Si is desirably used as the aluminum alloy. The peripheral wall 12 and the vane rotor 15 are formed by applying cutting work and polishing work to the roughly molded base material. The volume of respective ignition timing lag hydraulic chambers and respective ignition timing advance hydraulic chambers increases and decreases by changing the cutting length. Even if pressure of the hydraulic fluid is the same, the torque for relatively rotatably driving the vane rotor 15 to the housing member can be changed, by changing the volume of the hydraulic chambers.

摘要： PROBLEM TO BE SOLVED: To provide a miniaturizable timing adjusting device having good sealability and fewer components. SOLUTION: A shoe housing 3 comprises a peripheral wall 4 and a front plate 5, and is integrally formed by aluminum die casting. The shoe housing 3 is formed separately from a timing gear 1. The shoe housing 3 and the timing gear 1 constitute a housing member, so that the number of components is reduced and the sealability is improved. Outer diameter of the timing gear 1 can be decreased regardless of the outer diameter of the shoe housing 3. A seal member 16 is arranged in a sliding part between the peripheral wall 4 and a vane rotor 9. The seal member 16 is mainly made of PPS resin, and inorganic filler harder than the PPS resin is mixed to it. The PPS resin and the mixed inorganic filler are softer than the shoe housing 3, so that abrasion amount of the peripheral wall 4 is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a small and easily workable valve timing control device. SOLUTION: Each vane of a vane rotor 15 is relatively turnably accommodated in an accommodating chamber 50 formed between each of shoes of a shoe housing 12. A sealing member 25 is fitted to a recessed part formed in vanes 15a, 15b, 15c, 15d. A sealing member 26 is fitted to a projecting part formed on an inner peripheral side of shoes 12a, 12b, 12c, 12d. Micro clearance is provided between an outer peripheral wall of the vane rotor 15 and an inner peripheral of the shoe housing 12, and the sealing members 25, 26 prevent leakage of hydraulic fluid between hydraulic chambers through the clearance. Since the sealing member 26 is fitted to each shoe even the valve timing control device is miniaturized and width of each shoe in rotating direction becomes narrow, the sealing member 26 always slides on an outer peripheral surface of a boss part 15f. The leakage of the hydraulic fluid can be thereby prevented between the hydraulic chambers.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic driving device capable of increasing attracting force without becoming large-size, and a solenoid valve using it. SOLUTION: A fixed core 13 is integrally formed with a storage part 14 for accommodating and supporting a plunger 17 in a freely reciprocated manner, and an attracting part 16 generating the force of attracting the plunger 17. The storage part 14 supports the plunger 17 in the freely reciprocated manner. The plunger 17 has a movable care 18 formed of a magnetic substance, and a cup 20 fitted to the movable core 18. The cup 20 is integrally formed with a cylindrical part 21 covering the outer peripheral side face of the movable core 18, and a bottom part 22 covering the attracting side end face of the movable core 18. An air gap between the magnetic parts of the storage part 14 and movable core 18 can be reduced by minimizing the thickness of the cup 20. Attracting force for attracting the plunger 17 can thereby be increased without increasing the turns of the coil 20.

Since a sliding surface of the sealing member 26, sliding on an outer peripheral surface of a boss part 15f of the vane rotor 15 formed in a convex surface, is formed in a concave surface, the sealing member 26 is prevented from being inclined by sliding resistance.

摘要： PROBLEM TO BE SOLVED: To provide a valve-timing adjusting device which is of simple construction, and which is capable of being machined with high accuracy. SOLUTION: A peripheral wall 4 of a shoe-housing 3 is formed integral with a front plate 5. The outside diameter L1 of the peripheral wall 4 on the front plate 5 side is larger than the outer diameter L2 on the anti-front plate side. The front plate 5 has a trace of gate cut at the corner part 50 on the peripheral wall 4 side, which is formed at the manufacturing time. Thus, defective seal due to chipping at the time of gate cut, can be prevented. Further, the inside diameter-wall surface of one side wall of a raw material can be machined on the reference of the outer wall face of the peripheral wall of the raw material, and after that, the outer wall face of the peripheral wall of the raw material or the inner peripheral wall face of the peripheral wall of the raw material after machining, the inner wall face of one side wall of the raw material, and the end face of an opening on the other side wall of the peripheral wall of the raw material, can be machined. Thus, the sealing property or the machining accuracy of the surface to be machined of the housing members, which has effects on the sliding wear between the members, is improved.
