Abstract

Claims (49)

1 . A valve, comprising:

an inlet;

an annular seat;

a poppet having an annular body having an inner volume having an open end and an annular seat facing surface selectively contactable with the annular seat, the annular seat facing surface facing away from the inner volume of the poppet with an inner end wall disposed therebetween and between the annular seat facing surface and the open end; and,

at least one alignment pin extending inwardly of the inner volume of the poppet;

an outlet fluidly connectable to the inlet; and

an alignment tube disposed between the outlet and the inlet, the alignment tube extending inwardly of the open end of the inner volume of the poppet and including an alignment feature thereon configured to at least partially receive the alignment pin therein when the annular seat-facing surface of the poppet is retracted from the seat.

2 . The valve of claim 1 , wherein:

the alignment tube further includes an alignment tube first end facing the inner end wall of the poppet, the alignment tube first end including the alignment feature thereon.

3 . The valve of claim 2 , wherein the alignment feature comprises at least one detent extending inwardly of the alignment tube first end face.

4 . The valve of claim 3 , wherein the pin is circular in cross section, and the detent has a curved surface extending inwardly of the alignment tube first end face.

5 . The valve of claim 2 , further including a pedestal base connected to the alignment tube distal to the alignment tube end face.

6 . The valve of claim 5 , wherein the pedestal base further includes at least one flow passage extending therethrough.

7 . The valve of claim 5 , further comprising a biasing member, in compression, extending between the pedestal base and the inner end wall of the poppet.

8 . The valve of claim 1 , wherein the inlet further comprises an inlet bore tapering inwardly on the direction of the outlet body.

9 . A valve, comprising:

an inlet;

an annular seat;

an outlet;

a poppet having an annular body having an inner volume, an annular first end wall and an annular second wall, the annular second wall facing the annular seat and selectively contactable with the annular seat, and an inner circumferential surface extending inwardly of the poppet from the first annular end wall;

a support tube extending inwardly of the inner volume of the poppet, the support tube including an outer circumferential wall having a circumference less than the circumference of the inner circumferential surface of the poppet such that a gap is present therebetween; and

a wiper disposed adjacent the first annular wall of the poppet an including a circumferential seal spanning the gap between an inner circumferential surface of the poppet and a first outer circumferential surface of the support tube.

10 . The valve of claim 9 , further comprising:

the support tube includes a first end facing the inlet, a second end facing the outlet, and a passage extending within the support tube between the first end and the second end thereof.

11 . The valve of claim 10 , wherein the passage includes a breather bore located adjacent to the first end of the support tube; and

a breather is disposed in the breather bore.

12 . The valve of claim 11 , wherein the passage includes a spring recess extending inwardly of the second end thereof;

the poppet includes an inner end wall bounding the inner volume of the poppet distal to the first annular end wall of the poppet;

the support tube includes a base portion having a greater circumference than the first outer circumferential surface of the support tune, the base portion including an annular support wall; and

a biasing member extends between the annular support wall and the inner end wall of the poppet.

13 . A valve, comprising;

a housing having a central through bore, a first threaded housing end and a second threaded housing end;

a first body having a first body flow passage and a first body threaded end, and a first attachment surface disposed between the first threaded end and the first body flow passage;

a second body having a second body flow passage and a second body threaded end, and a second attachment surface disposed between the second threaded end and the second body flow passage;

the first body threaded end received in the first threaded housing and, and a first retainer extending from the housing and into contact with the first attachment surface; and

the second body threaded end received in the second threaded housing and, and a second retainer extending from the housing and into contact with the second attachment surface.

14 . The valve of claim 13 , wherein the hosing further comprises at least one first through threaded passage extending therethrough and the first retainer includes an outer threaded surface and is received in the first through threaded passage.

15 . The valve of claim 13 , wherein the second body includes an outer circumferential surface and a circumferential flange extending outwardly from the outer circumferential surface, the circumferential; and

a connector comprising an inner annular threaded surface and an inwardly extending ledge.

16 . A valve, comprising:

a housing having a central through bore, a first housing open end and a second housing open end;

a first body having a first body flow passage and a retaining ring counterbore, at least a portion of the first body received in the first housing open end;

a second body having a second body flow passage and at least a portion of the second body received in the first housing open end;

a seat assembly comprising a first retaining ring, a second retaining ring, and a seat supported by the first retaining ring and the second retaining ring; and

a poppet reciprocally received in the housing.

17 . The valve of claim 16 , wherein the first retaining ring includes an alignment boss extending inwardly of the retaining ring counterbore in the first body.

18 . The valve of claim 16 , wherein the first retaining ring further comprises a circumferential ledge bounding an annular seat and second retaining ring contacting surface, and the circumferential ledge includes a protrusion thereon extending inwardly of the seat.

19 . The valve of claim 18 , wherein the annular seat and second retaining ring contacting surface includes a circumferential relief recess extending inwardly thereof.

20 . The valve of claim 16 , wherein the seat further includes a through flow passage and an outer circumferential surface, the outer circumferential surface including a spacing wall and a circumferential rounded protrusion extending radially outwardly from the spacing wall, an first annular tapered surface facing the first retaining ring and a second tapered annular surface facing the poppet.
