An assembly for pre-stressing a canister within a magnetically coupled device comprising:
- a housing body having at least one housing portion;
- a housing head connectable to said housing body;
- a canister having a side wall, an open end and a closed end;
- said canister connectable to said at least one housing portion of said housing body adjacent said canister open end;
- a pin and pin plate combination disposed between said housing head and said canister closed end;
- and wherein said at least one housing portion, said housing head, said pin and pin plate combination and said canister are adapted to cause said canister to stretch in a longitudinal direction when said housing head and said canister are connected in sealing engagement with said housing body.
A method of pre-stressing a canister within a magnetically coupled device comprising the steps of:
- selecting a housing body having at least one housing portion and a housing head that is connectable to said housing body;
- selecting a canister having a side wall, an open end and a closed end;
- selecting a pin and pin plate combination and positioning said pin and pin plate combination between said housing head and said canister closed end;
- and connecting the canister adjacent the canister open end to the housing body in sealing engagement with said housing body and connecting said housing head to said housing body in sealing engagement with said housing body, thereby moving said pin and pin plate combination toward said closed end of said canister and causing said canister to stretch in a longitudinal direction.
A method of pre-stressing a canister within a magnetically coupled device comprising the steps of:
- selecting a housing body of a magnetically coupled device having at least one housing portion;
- selecting a housing head that is connectable to said housing body, and a canister that is connectable to said housing body;
- selecting and placing a pin portion and a pin plate portion in respective positions wherein the pin plate portion will engage an inner end wall of the canister while a first end of the pin portion will engage the pin plate portion and a second end of the pin portion will engage the housing head;
- connecting the canister and housing head to the housing body and in sealing engagement with the housing body, thereby stretching the canister in a longitudinal direction.
