摘要： A stator is provided with a ring-shaped outer stator-projection and a ring-shaped inner stator-projection. A plunger is provided with a ring-shaped outer plunger-projection and a ring-shaped inner plunger-projection. A magnetic force is generated at three portions between the plunger and the stator. The inner stator-projection has a first tapered surface and the outer plunger-projection has a second tapered surface. The first tapered surface and the second tapered surface confront each other when the plunger moves toward the stator.

摘要： A bobbin and a magnetic transmitting/receiving stator are positioned by fitting two positioning projections provided for a bobbin flange into two positioning holes formed in a stator flange. The positioning hole has a circular shape and the positioning projection has a flat oval shape which matches a diameter part of the circular shape so that a resin-passing gap is formed between the shapes. Since the resin-passing gap plays the role equivalent to the role of a resin passing hole, the total number of positioning holes and the resin passing holes can be reduced, and magnetic flux passing through the stator flange can be prevented from decreasing. Since a post-forming resin flows through the resin-passing gap in the positioning part, the flow of the post-forming resin can be made uniform in the whole periphery, and occurrence of poor molding can be restricted.
摘要翻译：通过将形成于筒管法兰的两个定位突起装配到形成在定子凸缘中的两个定位孔中来定位线轴和磁性传递/接收定子。定位孔具有圆形形状，并且定位突起具有与圆形直径部分匹配的扁平椭圆形状，使得在形状之间形成树脂通过间隙。由于树脂通过间隙起到与树脂通孔的作用相当的作用，因此可以减少定位孔和树脂通孔的总数，并且可以防止通过定子凸缘的磁通量减少。由于后成型树脂流过定位部分中的树脂通过间隙，所以后整形树脂的流动可以在整个周边上均匀，并且可以限制发生差的成型。

摘要： A plunger main body is fixed to a shaft to reciprocate together with the shaft in an axial direction within a predetermined range. An axial overlapped surface area between a rear stator main body and the plunger main body is reduced when the plunger main body is moved from a rear stator main body side toward a front stator main body side. A plunger projection radially outwardly projects from an outer peripheral wall of an end portion of the plunger main body, which is axially located on the rear stator main body side.

摘要： A valve timing control apparatus includes a linear solenoid having a coil, a casing, a needle, a pair of cylindrical stators and a cylindrical spacer. The pair of cylindrical stators oppose with each other through an air gap in an axis direction. The pair of stators and the needle form a magnetic circuit so as to drive the needle to reciprocate. The cylindrical spacer fits with an outer circumference side of the pair of stators so as to restrict a short circuit from being generated in the magnetic circuit between the pair of stators. The spacer defines a discharge passage that connects the air gap to a discharge port of the casing.

摘要： A check valve is provided in a fluid passage between a phase change valve and a fluid supply source. The check valve enables a flow of the hydraulic fluid from the fluid supply source to a retarding chamber or an advancing chamber defined in a housing in corporation with a vane rotor received therein. The check valve blocks a flow of the hydraulic fluid from the retarding chamber or the advancing chamber to a fluid supply source side. A filter is provided in the fluid passage between the check valve and the fluid supply source to remove debris from the hydraulic fluid before supplying of the hydraulic fluid to the check valve.

摘要： An electromagnetic valve device reduces wear of a moving member and a non-magnetic member sliding against the moving member and prevents contamination from contacting the sliding part. The moving member is directly and movably supported in a reciprocating manner by a non-magnetic cup. The moving member has a hard layer made of nickel containing PTFE (polytetrafluoroethylene) particles at the sliding part located against the cup. The hardness of the hard layer is high and is approximately the hardness of the stainless steel cup. Therefore, the wear of both the moving member and the cup can be reduced. The hard layer contains the PTFE particles, and therefore the sliding part between the moving member and the cup is lubricated by the PTFE, which reduces the sliding resistance at the sliding part and improves the responsiveness of the device.
摘要翻译：电磁阀装置减少了移动构件和抵靠移动构件滑动的非磁性构件的磨损，并防止污染物接触滑动部件。移动构件通过非磁性杯直接且可移动地以往复方式支撑。移动构件在位于杯子的滑动部分处具有由含有PTFE（聚四氟乙烯）颗粒的镍制成的硬层。硬质层的硬度高，大约是不锈钢杯的硬度。因此，可以减少移动构件和杯的磨损。硬质层包含PTFE颗粒，因此移动构件与杯之间的滑动部分由PTFE润滑，这降低了滑动部分的滑动阻力，提高了装置的响应性。
