Abstract

An anti-leak adaptor for use in a vehicle during an air conditioning system evaluation includes a cylindrically shaped adaptor body having a first end and a second end. A central passageway extends between an opening in the first end to an opening in the second end. The first end includes a guide portion and a threaded portion that is adjacent the guide portion. A knob is positioned on a mid-portion of the adaptor body, and the knob is operatively connected to a plunger disposed within the central passageway in the adaptor body and oriented longitudinally towards the opening in the first end. A fitting is connected to the second end of the adaptor body for receiving a sensing means.

Claims

1. A anti-leak adaptor for use in a vehicle during an air conditioning system evaluation, said adaptor comprising:

a cylindrically shaped adaptor body having a first end and a second end and a central passageway extending between an opening in the first end to an opening in the second end, wherein said first end includes a guide portion and a threaded portion that is adjacent the guide portion;

a knob positioned on a mid-portion of the adaptor body, wherein said knob is operatively connected to a plunger disposed within the central passageway in said adaptor body and oriented longitudinally towards the opening in said first end;

a fitting connected to said second end of said adaptor body for receiving a sensing means.

2. The anti-leak adaptor of claim 1 further comprising a sealing means positioned over an outer surface of said first end of said adaptor body.

3. The anti-leak adaptor of claim 1 wherein said fitting includes a housing having a cylindrical shape, and said sensing means is threadingly connected to said fitting.

4. The anti-leak adaptor of claim 1 wherein said guide portion of said adaptor body is operatively connected to a receiving end of a service valve disposed in a line in a vehicle air conditioning system, and rotation of said knob displaces said plunger to actuate said service valve.

5. An anti-leak adaptor for use in a vehicle during an air conditioning system evaluation, said adaptor comprising:

an adaptor body having a cubical shape, with a first wall, an opposed second wall, and a third wall that is perpendicular to said first and second walls, and each of the walls includes an opening, wherein a first passageway extends between the first opening in the first wall to the second opening in the second wall, and a second passageway extends between the third opening in said third wall and first passageway;

a first fitting adjacent to the first opening in said first wall of the adaptor body, wherein said first fitting is generally cylindrical and includes a passageway that is contiguous with the first passageway in the adaptor body;

a second fitting located adjacent said second wall of said adaptor body, wherein said second fitting includes a passageway that is contiguous with the first passageway in the adaptor body;

a knob operatively connected to said second fitting, wherein said knob includes a plunger disposed within the central passageway in said adaptor body and oriented longitudinally towards the first opening in said first wall; and

a third fitting connected to said third wall of said adaptor body for receiving a sensing means.

6. The anti-leak adaptor of claim 5 further comprising a sealing means positioned over an outer surface of said first end of said adaptor body.

7. The anti-leak adaptor of claim 5 wherein said third fitting includes a housing having a cylindrical shape, and an outer surface of said fitting is threaded and said sensing means is threadingly connected to said fitting.

8. The anti-leak adaptor of claim 5 wherein said third fitting includes a housing having a cylindrical shape, and an inner surface of said fitting is threaded and said sensing means is threadingly connected to said fitting.

9. The anti-leak adaptor of claim 5 wherein an outer surface of said first fitting is threaded, and said first fitting is threadably connected to a receiving end of a service valve disposed in a line in a vehicle air conditioning system, and rotation of said knob displaces said plunger to actuate said service valve.

10. An anti-leak adaptor for use in a vehicle during an air conditioning system evaluation, said adaptor comprising:

an adaptor body having a cubical shape, with a first wall, an opposed second wall, and a third wall that is perpendicular to said first and second walls, and each of the walls includes an opening, wherein a first passageway extends between the first opening in the first wall to the second opening in the second wall, and a second passageway extends between the third opening in said third wall and first passageway;

a first fitting adjacent to the first opening in said first wall of the adaptor body, wherein said first fitting is generally cylindrical and includes a passageway that is contiguous with the first passageway in the adaptor body, and an outer surface of said first fitting is threaded;

a second fitting located adjacent said second wall of said adaptor body, wherein said second fitting includes a passageway that is contiguous with the first passageway in the adaptor body;

a knob operatively connected to said second fitting, wherein said knob includes a plunger disposed within the central passageway in said adaptor body and oriented longitudinally towards the first opening in said first wall; and

a third fitting connected to said third wall of said adaptor body for receiving a sensing means, wherein said first fitting is threadably connected to a receiving end of a service valve disposed in a line in a vehicle air conditioning system, and rotation of said knob displaces said plunger to actuate said service valve.

11. The anti-leak adaptor of claim 10 further comprising a sealing means positioned over an outer surface of said first end of said adaptor body.

12. The anti-leak adaptor of claim 10 wherein said third fitting includes a housing having a cylindrical shape, and an outer surface of said fitting is threaded and said sensing means is threadingly connected to said fitting.

13. The anti-leak adaptor of claim 10 wherein said third fitting includes a housing having a cylindrical shape, and an inner surface of said fitting is threaded and said sensing means is threadingly connected to said fitting.
