Abstract

A fluid coupler includes a housing with an inlet port and an outlet port, a piston disposed in the housing and configured to control fluid flow between the inlet port and the outlet port, and a piston retainer disposed in the housing. A piston may include at least one radially-extending support member, and the radially-extending support member may include an aperture. The at least one radially-extending support member may be substantially planar.

First claim

What is claimed is:

1 . A fluid coupler, comprising:
a housing including an inlet port and an outlet port; a piston disposed in the housing and configured to control fluid flow between the inlet port and the outlet port; and a piston retainer disposed in the housing; wherein the piston includes at least one radially-extending support member, and a radially-extending support member of the at least one radially-extending support member includes an aperture.

2 . The fluid coupler of claim 1 , wherein the at least one radially-extending support member is substantially planar.

3 . The fluid coupler of claim 1 , wherein the at least one radially-extending support member is substantially parallel to a plane defined by an axial direction and a radial direction relative to a central axis of the piston.

4 . The fluid coupler of claim 1 , wherein the at least one radially-extending support member includes four radially-extending support members.

5 . The fluid coupler of claim 1 , wherein the aperture includes a first portion and a second portion, and the first portion includes a greater axial extent than the first portion.

6 . The fluid coupler of claim 1 , wherein the aperture includes a radial extent that is at least half as a radial extent of the radially-extending support member.

7 . The fluid coupler of claim 1 , wherein the piston is keyed with a connecting member; and the connecting member is disposed at partially in an inner portion of the piston and at least partially in a collar of the piston retainer.

8 . The fluid coupler of claim 1 , wherein the piston is configured to translate within the housing and is prevented from rotating relative to the housing.

9 . The fluid coupler of claim 1 , including a fluid straightener.

10 . The fluid coupler of claim 9 , wherein the piston is configured as the fluid straightener, the at least one radially-extending support member includes at least six radially-extending support members equally circumferentially-spaced about at least one of (i) an inner surface of an outer wall of the piston and (ii) an inner portion of the piston.

11 . A piston for a fluid coupler, the piston comprising:
an outer wall including a cylindrical configuration; an inner portion; and a plurality of support members extending between the cylindrical outer wall and the inner portion; wherein at least one of the plurality of support members includes an aperture.

12 . The piston of claim 11 , wherein the at least one support member is radially-extending and is substantially planar.

13 . The piston of claim 11 , wherein the at least one support member is substantially parallel to a plane defined by an axial direction and a radial direction relative to a central axis of the piston.

14 . The piston of claim 11 , wherein the plurality of support members includes at least three support members.

15 . The piston of claim 11 , wherein the aperture includes a first portion and a second portion, and the first portion includes a greater axial extent than the first portion.

16 . The piston of claim 15 , the second portion includes a greater radial extent than the first portion.

17 . The piston of claim 15 , wherein the first portion is disposed at a first distance from the outer wall, the second portion is disposed at a second distance from the outer wall, and the second distance is greater than the first distance.

18 . The fluid coupler of claim 11 , wherein the aperture includes an L-shaped configuration.

19 . The fluid coupler of claim 11 , wherein the aperture includes a radial extent that is at least half as great as a radial extent of the at least one support member.

20 . The fluid coupler of claim 11 , wherein the inner portion includes a recess configured to engage a key of a connecting member.
