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 converter includes a plurality of ports provided to a housing, a plurality of conversion circuit electrically connected to the respective ports, and a plurality of coils electrically connected to the respective power conversion circuits and wound around a transformer core. The plurality of coils including a predetermined first coil electrically connected to a predetermined conversion circuit and a second coil. The conversion circuit is mounted to a predetermined board, while the first coil is fixed along the periphery of a board hole of the predetermined board. The predetermined board is fixed to the housing in the state in which the transformer core is inserted into the board hole to determine the position of the predetermined coil relative to the second coil.

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).

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.
