Abstract

A nozzle cap spacer for a hydrant nozzle cap includes a spacer body defining an outer edge and an inner edge, the inner edge defining an opening formed through a center of the spacer body; and a leak path notch formed in the spacer body, the leak path notch extending radially inward from the outer edge of the spacer body.

First claim

That which is claimed is:

1. A spaced nozzle cap assembly comprising:
a nozzle cap comprising a cap body, the cap body comprising a bore sidewall defining a bore, the bore sidewall further defining a leak channel; and
a nozzle cap spacer received within the bore and defining an outer edge, a leak path notch extending into the nozzle cap spacer at the outer edge, the leak path notch aligned with the leak channel;
wherein:
the cap body defines a first body end and a second body end;
the bore extends from the second body end of the cap body to an inner wall of the cap body;
the leak channel extends substantially from the second body end to the inner wall; and
a front spacer surface of the nozzle cap spacer abuts the inner wall.

2. The spaced nozzle cap assembly of claim 1 , wherein:
the bore sidewall defines internal threading and an annular recess;
the leak channel cuts across at least the internal threading;
the annular recess is oriented between the internal threading and the inner wall; and
the nozzle cap spacer is disposed within the annular recess.

3. The spaced nozzle cap assembly of claim 2 , wherein:
the leak channel defines a first leak channel segment and a second leak channel segment;
the first leak channel segment is formed in the inner wall; and
the second leak channel segment is formed in the bore sidewall and is connected to the first leak channel segment.

4. The spaced nozzle cap assembly of claim 1 , wherein:
the nozzle cap comprises an antenna; and
the nozzle cap spacer is configured to adjust a rotational indexing of the nozzle cap to reorient the antenna.

5. The spaced nozzle cap assembly of claim 1 , wherein the nozzle cap spacer further defines an inner edge, the inner edge defining an opening formed through a center of the nozzle cap spacer, the leak path notch extending radially inward from the outer edge of the nozzle cap spacer towards the inner edge.

6. The spaced nozzle cap assembly of claim 5 , wherein the nozzle cap spacer is a gasket spacer comprising a compressible, resilient material.

7. The spaced nozzle cap assembly of claim 5 , wherein the nozzle cap spacer defines the front spacer surface and a rear spacer surface opposite the upper front spacer surface:
a thickness of the nozzle cap spacer is defined between the front spacer surface and the rear spacer surface;
and the leak path notch extends from the front spacer surface to the rear spacer surface.

8. A spaced nozzle cap assembly comprising:
a nozzle cap comprising a cap body, the cap body comprising a bore sidewall defining a bore, the bore sidewall further defining a leak channel; and
a nozzle cap spacer received within the bore and defining an outer edge, a leak path notch extending into the nozzle cap spacer at the outer edge, the leak path notch aligned with the leak channel;
wherein:
the nozzle cap comprises an antenna; and
the nozzle cap spacer is configured to adjust a rotational indexing of the nozzle cap to reorient the antenna.

9. The spaced nozzle cap assembly of claim 8 , wherein:
the cap body defines a first body end and a second body end;
the bore extends from the second body end of the cap body to an inner wall of the cap body;
the leak channel extends substantially from the second body end to the inner wall; and
a front spacer surface of the nozzle cap spacer abuts the inner wall.

10. The spaced nozzle cap assembly of claim 9 , wherein:
the bore sidewall defines internal threading and an annular recess;
the leak channel cuts across at least the internal threading;
the annular recess is oriented between the internal threading and the inner wall; and
the nozzle cap spacer is disposed within the annular recess.

11. The spaced nozzle cap assembly of claim 10 , wherein:
the leak channel defines a first leak channel segment and a second leak channel segment;
the first leak channel segment is formed in the inner wall; and
the second leak channel segment is formed in the bore sidewall and is connected to the first leak channel segment.

12. The spaced nozzle cap assembly of claim 8 , wherein the nozzle cap spacer further defines an inner edge, the inner edge defining an opening formed through a center of the nozzle cap spacer, the leak path notch extending radially inward from the outer edge of the nozzle cap spacer towards the inner edge.

13. The spaced nozzle cap assembly of claim 12 , wherein the nozzle cap spacer is a gasket spacer comprising a compressible, resilient material.

14. The spaced nozzle cap assembly of claim 12 , wherein
the nozzle cap spacer defines a front spacer surface and a rear spacer surface opposite the front spacer surface;
a thickness of the nozzle cap spacer is defined between the front spacer surface and the rear spacer surface; and
the leak path notch extends from the front spacer surface to the rear spacer surface.
