Abstract
A solenoid valve has a solenoid component having at least one plunger. At least one valve component having a housing and a piston slidably mounted in the housing is provided. The at least one valve component and the solenoid component are connected to one another. At least one seal, connected to the solenoid component or the at least one valve component, is provided for sealing the solenoid valve relative to a support on which the solenoid valve is mounted.
Claims26
A solenoid valve comprising:
- a solenoid component (3) having at least one plunger (28);
- at least one valve component (4) having a housing (26) and a piston (27) slidably mounted in said housing (26), wherein said housing (26) of said at least one valve component (4) has a widened portion (30) projecting into a housing (5, 52) of said solenoid component (3), wherein said widened portion (30) is a unitary part of said housing (26) of said at least one valve component (4), and wherein said widened portion is a magnetic ground element;
- said at least one valve component (4) and said solenoid component (3) connected to one another;
- at least one seal (31, 54), connected to said solenoid component (4) or
- said at least one valve component, sealing said solenoid valve relative to a support on which said solenoid valve is mounted.
