Abstract

This invention relates to a canister retainer assembly for holding an aerosol canister of starting fluid in an upright position against a mechanical or an electrical valve. This canister retainer assembly is comprised of an adapter and a canister holder. The adapter is securely attached at one end to the mechanical or electrical valve and is opened at the other end. Located near the open end of the adapter is an attachment means, such as internal threads. The canister holder, which is comprised of a hollow tubular member with an open end and a closed end, is designed to be joined to the adapter by external attachment means. Such an assembly is capable of both holding an aerosol canister in an upright position against a diesel engine and of being inverted to seal off the inlet opening of the mechanical or electrical valve when no canister is present.

Claims

1. A canister retainer assembly capable of holding an aerosol canister in an upright position against an electric solenoid valve associated with an engine and of sealing said electric solenoid valve from outside air when no canister is present, said electric solenoid valve including an inlet opening, a rubberized gasket surrounding said inlet opening, a plunger movably positioned within said inlet opening, and means for activating said plunger to contact an outlet valve located in the top of said aerosol canister to release pressurized fluid from said aerosol canister, said assembly comprising:

(a) a collar-shaped adapter secured to said electric solenoid valve which has an end surface with an opening therein, said adapter further having threads formed on an inner circumferential surface approximate said open end; and

(b) a canister holder having a hollow cylindrical body which is opened at one end and closed at a second end, and further having first and second spaced apart helical threads formed on the outer circumference thereof such that said first threads are located adjacent to said open end and said second threads are located adjacent to said closed end, said first threads being engageable with said threads formed on said adapter to position said holder in a first position wherein said holder is capable of retaining said aerosol canister in an upright position against said electric solenoid valve and said second threads being engageable with said threads formed on said adapter to position said holder in a second position wherein said holder is inverted 180 degrees to seal said electric solenoid valve from contamination when no aerosol canister is present.

2. The canister retainer assembly of claim 1 wherein said first and second threads are right-hand threads.

3. The canister retainer assembly of claim 1 wherein said first and second threads are left-hand threads.

4. The canister retainer assembly of claim 1 wherein said closed end of said canister holder has an external convex configuration for aiding in sealing said valve from outside air when said canister holder is in said second position.

5. The canister retainer assembly of claim 1 wherein said first thread is spaced a set distance away from said open end and said second thread is spaced an equal distance away from said closed end.

6. A canister retainer assembly capable of holding an aerosol canister in an upright position against an electric solenoid valve associated with an engine and of sealing said electric solenoid valve from an outside air when no canister is present, said electric solenoid valve including an inlet opening, a rubberized gasket surrounding said inlet opening, a plunger movably positioned within said inlet opening, and means for activating said plunger to contact an outlet valve located in the top of said aerosol canister to release pressurized fluid from said aerosol canister, said assembly comprising:

(a) a collar-shaped adapter secured to said electric solenoid valve which has an end surface with an opening therein, said adapter further having threads formed on an inner circumferential surface approximate said open end;

(b) a canister holder having a hollow cylindrical body which is opened at one end and closed at a second end, and further having first and second spaced apart helical threads formed on the outer circumference thereof such that said first threads are located adjacent to said open end and said second threads are located adjacent to said closed end, said first threads being engageable with said threads formed on said adapter to position said holder in a first position wherein said holder is capable of retaining said aerosol canister in an upright position against said electric solenoid valve and said second threads being engageable with said threads formed on said adapter to position said holder in a second position wherein said holder is inverted 180 degrees to seal said electric solenoid valve from contamination when no aerosol canister is present; and

(c) a pair of oppositely aligned circumferential openings formed in said canister holder for facilitating viewing of a retained aerosol canister when said canister holder is in said first position.

7. The canister retainer assembly of claim 6 wherein said closed end of said canister holder has an external convex configuration.

8. A canister retainer assembly for an engine, said engine having a valve associated therewith which has an inlet opening, a plunger movably positioned within said inlet opening, and means for activating said plunger to contact an outlet valve located in the top of an aerosol canister to release pressurized fluid into said engine, said assembly comprising:

(a) a collar-shaped adapter secured to said valve which has an end surface with an opening therein, said adapter further having threads formed on an inner circumferential surface approximate said open end; and

(b) a canister holder having a hollow cylindrical body which is opened at one end and closed at a second end, and further having first and second spaced apart threads formed on the outer circumference thereof such that said first threads are located adjacent to said open end and said second threads are located adjacent to said closed end, said first threads being engageable with said threads formed on said adapter to position said holder in a first position wherein said holder is capable of retaining said aerosol canister in an upright position against said valve and said second threads being engageable with said threads formed on said adapter to position said holder in a second position wherein said holder is inverted 180 degrees to seal said valve from contamination when no aerosol canister is present.
