Abstract
A method of making a valve (62) that has a poppet valve member (100) biased by a spring (110) toward a closed position against a poppet valve seat (90). The spring acts between the poppet valve member and a spring seat (120) and applies a predetermined force to the poppet valve member. The method comprises the steps of providing a valve housing (70) having a chamber (72); inserting into the chamber in sequential order the poppet valve seat (90), the poppet valve member (100), the spring (110), and the spring seat (120); applying a force to the spring seat to compress the spring a predetermined amount; and securing the poppet valve seat and the spring seat to the housing (70) while maintaining the spring compressed the predetermined amount.

A method of making a valve having a poppet valve member that is biased by a spring toward a closed position against a poppet valve seat, the spring acting between the poppet valve member and a spring seat and applying a predetermined force to said poppet valve member, said method comprising the steps of:
- providing a valve housing having a chamber;
- inserting into said chamber in sequential order said poppet valve seat, said poppet valve member, said spring, and said spring seat;
- applying a force to said spring seat to compress said spring a predetermined amount;
- and
- fixedly securing said poppet valve seat and said spring seat to said housing while maintaining said spring compressed the predetermined amount.
A method of making a valve comprising the steps of:
- providing a tubular housing having an end wall at one end of said tubular housing, said end wall having a first opening therethrough;
- inserting a poppet valve seat into said tubular housing through a second opening in said tubular housing at a second end of said tubular housing opposite said one end;
- inserting a poppet valve into said tubular housing into engagement with said poppet valve seat;
- inserting into said tubular housing a spring for biasing said poppet valve against said poppet valve seat,
- inserting into said tubular housing a spring seat against which said spring acts;
- compressing said spring a predetermined amount;
- deforming a first part of said tubular housing into locking engagement with said poppet valve seat to fixedly secure said tubular housing and poppet valve seat together while maintaining said spring compressed the predetermined amount;
- and
- deforming a second part of said tubular housing into locking engagement with said spring seat to fixedly secure said tubular housing and spring seat together while maintaining said spring compressed the predetermined amount.
