Abstract
(EN)
An electromagnetic three-way valve (V) has a valve seat (3) and an outlet port (2) that are arranged at one end of a valve box (1), a valve seat (5) located at a position separated from the one end, a valve body (10) reciprocably placed in the valve box (1), an electromagnetic coil section (8) placed at the other end of the valve box (1) and having the valve body (10) and a plunger (10A), a sealing annular projection (23) for sealing between the valve box (1) and the valve body (10) to partition the inner space of the valve box (1) into a first chamber (M1) facing the valve seat (3) and a second chamber (M2) facing the valve seat (5), a first inlet port (25) open in the first chamber (M1), and an inlet port (26) open in the second chamber (26). When the valve body (10) comes into contact with the valve seat (5), the inlet port (25) and the outlet port (2) are interconnected, and when the valve body (10) comes into contact with the valve seat (3), the inlet port (26) and the outlet port (2) are interconnected through an internal flow path (11). The valve body (10) can be slid by magnetic force, and as a result, the valve has a simplified structure and enhanced reliability.

L'invention concerne une soupape électromagnétique à trois voies (V) qui a un siège de soupape (3) et un orifice de sortie (2) qui sont disposés au niveau d'une extrémité d'un boîtier de soupape (1), un siège de soupape (5) situé à une position séparée de l'extrémité, un corps de soupape (10) placé dans le boîtier de soupape (1) de façon à pouvoir se déplacer en va-et-vient, une section de bobine électromagnétique (8) placée à l'autre extrémité du boîtier de soupape (1) et ayant le corps de soupape (10) et un piston (10A), une saillie annulaire d'étanchéité (23) pour une étanchéité entre le boîtier de soupape (1) et le corps de soupape (10) afin de séparer l'espace interne du boîtier de soupape (1) en une première chambre (M1) tournée vers le siège de soupape (3) et une seconde chambre (M2) tournée vers le siège de soupape (5), un premier orifice d'entrée (25) débouchant dans la première chambre (M1) et un orifice d'entrée (26) débouchant dans la seconde chambre (26). Lorsque le corps de soupape (10) vient en contact avec le siège de soupape (5), l'orifice d'entrée (25) et l'orifice de sortie (2) sont interconnectés, et lorsque le corps de soupape (10) vient en contact avec le siège de soupape (3), l'orifice d'entrée (26) et l'orifice de sortie (2) sont interconnectés par l'intermédiaire d'un trajet d'écoulement interne (11). Le corps de soupape (10) peut être amené à coulisser par une force magnétique et, par suite, la soupape a une structure simplifiée et une fiabilité améliorée.
