Claims19
A valve assembly comprising:
- a one-piece collar-tube including a collar portion and a tube portion;
- an inlet;
- an outlet;
- a valve seat disposed within the collar portion in the flow path between the inlet and the outlet;
- a stationary core disposed within the tube portion;
- a moveable valve member disposed within the one-piece collar-tube and moveable relative to the valve seat;
- a biasing element disposed within the tube portion for resiliently biasing the moveable valve member relative to the valve seat;
- and
- a solenoid disposed around the tube portion, the solenoid operable for moving the valve member relative to the valve seat against the bias of the biasing element.
A one-piece collar-tube for a valve assembly, the one-piece collar-tube including a collar portion and a tube portion integrally formed from non-magnetic material such that the one-piece collar-tube has a monolithic construction.
A method comprising integrally forming a collar portion and a tube portion for a valve assembly from a non-magnetic material as a single piece having a monolothic construction without any welded, soldered, or brazed joints connecting the collar portion to the tube portion.
