More Information
Summary:The electromagnetic 3-way valve has a coil body (41) which has three openings (42-44), an excitation channel (41) which links these openings together, a first valve seat created in the channel between the first two openings, a second valve seat in the channel between the second and third openings and a ball-holding section which is provided at the end of the channel where the first opening is. A ball (51) is held in the section but able to move back and forth and can be brought into position at the first valve seat and away. A coil is in the coil body, and a piston (53) is inserted in the flow channel which possesses a pushrod (56) that is held against the ball, having a ball seat (54) which comes into position at the second valve seat or moves away according to the excitation state of the coil. A cross-section with a small diameter has a diameter that is smaller than that of the ball seat. It is present at a section of the piston lying in the flow channel between the second and third openings.
