ABSTRACT:
A solenoid valve comprising a housing having at least one cavity, a core assembly including a body, a sleeve attached to the body, and an armature assembly sliding in the sleeve. A core assembly is mounted in at least one cavity of the housing having a lower portion of the body between a side of the body exposed to atmosphere and a side exposed to fluid pressure in use being affixed to the housing by a primary caulking joint inside the cavity and a secondary caulking joint at a mouth of the housing cavity. A coil assembly is mounted on an exterior of38 the core assembly magnetically influencing the armature assembly. The primary caulking joint is formed between a pressure acting surface of the cavity of the housing and a primary sealing groove on the body. The primary caulking joint can be formed by inserting the body into the cavity; and then pressing the body further into the cavity, the pressure-acting surface pressing on a portion of the material of the housing causing the pressed-material to undergo plastic deformation and flow and mold into the primary sealing groove. The secondary caulking joint is formed by a lip of the cavity at the mouth and a ridge on the body.
