Abstract: A first resilient member generates a resilient force to urge a valve portion in a valve-closing direction. A second resilient member generates a resilient force against the resilient force of the first resilient member. The resilient force of the first resilient member and the resilient force of the second resilient member are set to be balanced with each other when the valve portion is placed in a lift position that is between a full-closing position of the valve portion, in which the valve portion is seated against a valve seat to fully close a fluid passage, and a full-opening position of the valve portion, in which the valve portion is fully lifted away from the valve seat to fully open the fluid passage.

Abstract: A partitioning wall is provided in a fluid space formed between a cover member and a body member, which surrounds a forward end of a fluid injection valve. The partitioning wall divides the fluid space into an inlet-side fluid space and an outlet-side fluid space in a circumferential direction of the fluid injection valve. A forward-end space, which is formed at a bottom of the fluid space, is communicated to the inlet-side and the outlet-side fluid spaces, so that cooling water flows from the inlet-side fluid space to the outlet-side fluid space through the forward-end space. The cooling water circulates in the forward-end space surrounding the forward end of the fluid injection valve to effectively cool down the fluid injection valve.

Abstract: A magnetic component includes a plurality of coils magnetically coupled with each other; and a core forming a closed magnetic circuit. At least part of portions in inner periphery side regions of respective plurality of coils are arranged overlapping with each other in a coil axial direction. When viewed from the coil axial direction, at least one of the coils is defined as a specific coil, and a region of the specific coil from an inner periphery edge to an outer periphery edge thereof in a coil radial direction is defined as a specific coil region, and the specific coil region has a portion which is not overlapped with at least one coil in the coil axial direction other than the specific coil that constitutes the specific coil region, in a region from the inner periphery edge to the outer periphery edge thereof in the coil radial direction.

Abstract: An electromagnetic valve includes a driving portion, a valve body, and a valve element. The driving portion generates a magnetic attractive force according to an energization. The valve body has an orifice through which a fluid flows, and a valve seat around an opening portion of the orifice. The valve element displaces according to the magnetic attractive force and a fluid force that is applied from the fluid, to vary a passage area between the valve element and the valve seat. When the valve element is placed at a position separated farthest from the valve seat, the passage area between the valve element and the valve seat is less than or equal to a passage area of the orifice.

Abstract: A power conversion apparatus (1) is used so as to be connected to three voltage units. The power conversion apparatus includes three power-conversion circuit units and a transformer (4). The three power-conversion circuit units are respectively connected to voltage units that differ from one another. Three coils (5) of the transformer (4) are connected to power-conversion circuit units that differ from one another. The three coils (5) are magnetically coupled with one another. The three coils (5) are arranged so as to be arrayed in a coil axial direction (z). One of the voltage units is a high-voltage battery. Among the coils other than a high-voltage battery-side coil (51) that is connected to the high-voltage battery, the coil (5) of which a power value that flows thereto is largest is arranged in a position that is adjacent to the high-voltage battery-side coil (51).
