Abstract: A solenoid valve for a pre-chamber of an internal combustion engine is provided. The solenoid valve may include a valve body defining an inlet port fluidly coupled with a fuel line, an outlet port fluidly coupled with the pre-chamber, and a passage fluidly coupling the inlet port with the outlet port. A valve stem may be slidably disposed in the passage between a first position and a second position. The valve stem may be configured to engage the outlet port in the first position to thereby prevent fluid communication therethrough. A biasing member may be disposed in the passage and configured to actuate the valve stem to the first position. A solenoid may be coupled with the valve body and configured to actuate the valve stem to the second position to thereby allow fluid communication therethrough.

Abstract: A electrical solenoid suitable for fluid controls applications with an elastomeric retaining device of an elastomeric material arranged between the housing and the lamination stack. The elastomeric retaining device eliminates the need for potting compound and the associated steps of filling the housing with potting and curing the potting compound. The solenoid has a wire coil wound about the lamination stack in which the wire coil has an electrical connection extending through the housing for electrical communication with an external electrical control. The end of the lamination stack projects out of the housing slightly after manufacturing and assembly. When the solenoid is mounted, the elastomeric retaining device biases the lamination stack against the mounting surface. The wire coil is pre-assembled in a wire coil assembly comprising a bobbin, a wire coil wound about the bobbin and a plastic overmold encapsulating the wire coil and bonded to the bobbin.
