Abstract

The invention relates to an electrovalve (1) having two states respectively corresponding to the opening and the closing of a duct (6, 6') in a hydraulic circuit, and including a coil (2) surrounding a fixed magnetic core (3), a mobile core (7), and a spring (11) provided between the fixed (3) and mobile (7) cores, the latter being capable of movement between a first stable position in the absence of current in the coil (2) and a second stable position opposite the spring (11) force when a current flows in the coil (2), the mobile core (7) is used as a valve in the hydraulic circuit, and is urged for closing the circuit against a seat comprising one part (13) provided in a housing (14) oriented in the movement direction of the mobile core (7), and having an outer shape such that it is connected to the walls of said housing (14) by a link of the ball and socket type, said part (13) protruding from the housing and having a planar surface (19) essentially perpendicular to the movement direction in order to engage, upon the closing, with a surface (20) of the mobile core (7) having the same orientation.
