Abstract

The present disclosure provides a male coupling member detachably couplable to a female coupling member that includes an outer coupling body having a first end inserted and fitted into the female coupling member, a second end opposite to the first end, and a passage extending from the first end to the second end. The male coupling member further includes an inner coupling body disposed coaxially with the outer coupling body at a position closer to the first end, and a filtration member detachably attached to the inner coupling body. The inner coupling body is attachable to and detachable from the outer coupling body from the first end. The filtration member is held in the passage when the inner coupling body is attached to the outer coupling body. The filtration member is detachable when the inner coupling body is detached from the outer coupling body.

First claim

What is claimed is:

1 . A male coupling member detachably couplable to an associated female coupling member, the male coupling member comprising:
an outer coupling body having a first end configured to be inserted into the female coupling member, a second end opposite the first end, and a passage extending from the first end to the second end in a direction parallel to a longitudinal axis; an inner coupling body coaxially disposed in the passage of the outer coupling body and detachably attached to the first end of the outer coupling body; and a filtration member detachably attached to at least one of the outer coupling body and the inner coupling body, wherein the filtration member is held in the passage of the outer coupling body when the inner coupling body is attached to the outer coupling body, and wherein the filtration member is detachable from the at least one of the outer coupling body and the inner coupling body when the inner coupling body is detached from the outer coupling body.

2 . The male coupling member of claim 1 , wherein the outer coupling body and the inner coupling body are cylindrical.

3 . The male coupling member of claim 1 , wherein the filtration member is detachably attached to the inner coupling body.

4 . The male coupling member of claim 3 further comprising a seal ring, wherein:
the inner coupling body has a nozzle insertion port configured to receive a nozzle distal end of the female coupling member, and
the seal ring is configured to be fitted to an inner peripheral surface of the nozzle insertion port of the inner coupling body.

5 . The male coupling member of claim 3 wherein:
the filtration member includes a cylindrical part, a downstream closing end portion, and a flange portion, wherein the cylindrical part has a filtration portion extending parallel to the longitudinal axis, the downstream closing end portion is operable to close the cylindrical part and is positioned between the filtration portion and second end of the outer coupling body, and the flange portion radially projects from the cylindrical part, and
the outer coupling body includes a retaining portion that extends radially inward from a peripheral wall surface of the passage and is positioned between the second end of the outer coupling body and the flange portion of the filtration member, wherein the flange portion and the retaining portion are configured to form an abutment to suppress displacement of the filtration member toward the second end of the outer coupling body in a direction parallel to the longitudinal axis.

6 . The male coupling member of claim 5 further comprising a seal ring, wherein:
the inner coupling body has a nozzle insertion port configured to receive a nozzle distal end of the female coupling member, and
the seal ring is configured to be fitted to an inner peripheral surface of the nozzle insertion port of the inner coupling body.

7 . The male coupling member of claim 5 , wherein the flange portion includes at least one through-hole extending therethrough in a direction parallel to the longitudinal axis, the through-hole constituting part of a fluid flow path.

8 . The male coupling member of claim 7 further comprising a seal ring, wherein:
the inner coupling body has a nozzle insertion port configured to receive a nozzle distal end of the female coupling member, and
the seal ring is configured to be fitted to an inner peripheral surface of the nozzle insertion port of the inner coupling body.

9 . The male coupling member of claim 1 , wherein the filtration member is detachably secured to a peripheral wall surface of the passage of the outer coupling body.

10 . The male coupling member of claim 9 further comprising a seal ring, wherein:
the inner coupling body has a nozzle insertion port configured to receive a nozzle distal end of the female coupling member, and
the seal ring is configured to be fitted to an inner peripheral surface of the nozzle insertion port of the inner coupling body.

11 . The male coupling member of claim 1 further comprising a seal ring, wherein:
the inner coupling body has a nozzle insertion port configured to receive a nozzle distal end of the female coupling member, and
the seal ring is configured to be fitted to an inner peripheral surface of the nozzle insertion port of the inner coupling body.
