摘要： The disclosure provides a pressure control device that improves the workability in assembling a body and a filter unit. The pressure control device includes a body and a filter unit. The body has a flow path that includes a groove and a widened part. The widened part is connected to the groove, extends to a bottom of the groove, and has a width larger than a width of the groove. The filter unit is housed along a depth direction of the widened part to capture foreign matter mixed in a fluid that passes through the flow path. The filter unit includes a cylindrical frame and a flat plate-shaped filter member, wherein the frame includes a through hole part that penetrates in a direction orthogonal to a central axis, and the filter member is disposed to block the through hole part.

摘要： The control valve device includes a valve body having a stacked first body and second body. The first body includes a first oil passage, a filter covering an opening of the first oil passage, a first accommodating part recessed from a first boundary surface surrounding the opening of the first oil passage, and two second accommodating parts which are more recessed than the first accommodating part from the first boundary surface on outer sides of opposite end portions of the first accommodating part. The filter includes a filter part covering the opening of the first oil passage and two leaf springs respectively disposed in the two second accommodating parts, and an end portion of each of the leaf springs comes into contact with a first wall surface of the second accommodating parts facing the first oil passage side.

摘要： A solenoid device includes a yoke, a core, a shaft, a bobbin, a coil, a plunger, a lid, and a housing. A housing body part of the housing has a first opening; a cylindrical first inner wall part having a first step part extending toward the outer side in the radial direction; and a cylindrical second inner wall part having a second step part extending toward the outer side in the radial direction. A first cylindrical part has a first flange part. The outer diameter of the first flange part is larger than the inner diameter of the first inner wall part and smaller than the inner diameter of the second inner wall part. A circumferential end part of the first flange part contacts the second step part. The lid is non-magnetic, and a circumferential edge part is held between the first step part and the first flange part.

摘要： An electromagnetic valve includes a pressing member fixed farther towards an electromagnetic movable section side than a valve chamber in a nozzle. The pressing member is fixed to a plunger farther towards the side where the plunger is pressed by the pressing member than a position where the pressing member is fixed to the nozzle. Thus, a magnetic circuit defined by magnetic flux that is generated from a magnet is prevented from being located at a portion not related to an attractive force between a core and the plunger such that it is possible to effectively utilize the magnetic flux as an attractive force between the core and the plunger.

摘要： A vehicle cooling system includes a circulation flow path section which has a first flow path section and a second flow path section, and a solenoid valve which can switch between an open state in which the first flow path section and the second flow path section are connected and a closed state in which the first flow path section and the second flow path section are blocked. The circulation flow path section includes a valve body accommodating section configured to include a first accommodating section and a second accommodating section which connects the first flow path section and the second flow path section in the open state, and a connection flow path section whose one end is connected to the first flow path section. The other end of the connection flow path section opens to the first accommodating section.

摘要： A solenoid device includes a yoke, a core, a shaft, a bobbin, a coil, a plunger, a lid, and a housing. A housing body part of the housing has a first opening; a first inner wall part expanding toward the outer side in the radial direction on an inner wall; and a first caulking part extending from the rear side end. The first inner wall part has a first step part extending toward the outer side in the radial direction at an end on the other side in the axial direction. A first cylindrical part of the yoke has a first flange part. The first flange part contacts the first step part with an end surface on the other side in the axial direction. The first caulking part is bent toward the inner side in the radial direction to contact a circumferential edge part of the lid.
