Electromagnetic linear valve

An electromagnetic linear valve comprising:

• a housing which includes a hollow cylindrical body portion, a core portion which closes an opening of one end portion of the body portion, a separation portion which separates an interior defined by the core portion and the body portion into a first liquid chamber located at one side of the separation portion nearer to the core portion and a second liquid chamber located at the other side of the separation portion, a through hole which passes through the separation portion so as to provide a communication between the first liquid chamber and the second liquid chamber, an outlet port which communicates with the first liquid chamber, and an inlet port which communicates with the second liquid chamber;
• a plunger which is disposed in the first liquid chamber such that the plunger is movable along an axis in a state in which one end portion of the plunger faces to the core portion and the other end portion of the plunger faces to an opening of the thorough hole, the other end portion being allowed to sit on the opening as a valve body,
• an elastic member which applies a force to the plunger in a first direction in which the one end portion of the plunger pulls away from the core portion and in which the other end portion of the plunger comes near to the opening, and
• a coil which is disposed around the housing and generates magnetic field to move the plunger against the force of the elastic member in a second direction in which the one end portion of the plunger comes near to the core portion and in which the other end portion of the plunger pulls away from the opening,
• wherein a recess is formed in a section of an inner circumferential portion of the body portion, the inner circumferential portion intersecting with an end face of the core portion, the end face being a face, in the first direction, nearer to the opening.
