- 1. A method of forming a plate valve comprising the steps of:
- a. forming fluid passage ports in a seat member,
- b. forming a rigid, movable plate member for controlling the flow of fluid through said ports;
- c. forming at least one projection on one side of said plate member
- d. mounting a flat spring plate in fixed relationship with respect to said seat member, and
- e. forming at least one flat resilient spring finger on said spring plate for contacting said at least one plate member projection to bias said plate member against and seal said fluid passage ports until sufficient fluid pressure in said ports forces said plate member against and bends said at least one flat spring finger thereby uncovering said fluid passage ports to allow fluid passage through said valve.
