Claim 4

The valve assembly of claim 1 wherein said sealing means includes annular flanges directed angularly and radially inwardly of said bore and engaging said valve member.

Claim 5

The valve assembly of claim 1 wherein said sealing means comprises trapezoidal grooves in said bore spaced axially thereof, each being defined by a pair of resilient deformable pressure flaps comprising opposed, annular flanges extending axially inwardly toward the center of said grooves and having free ends in spaced relationship defining an annular passageway between said groove and said bore, said flaps being in sealing engagement with said valve member.

Claim 6

The valve assembly of claim 1 wherein said sealing means comprises radially inwardly extending resilient annular flanges each received respectively in an annular groove in said bore, and an O-ring seal attached to each of said flanges and sealingly engaging said valve member.

Claim 7

The valve assembly of claim 5 wherein said valve member has a plurality of annular grooves therein for receiving said O-rings.

Claim 8

A valve assembly comprising a subplate manifold having a plurality of openings to a first surface thereof, a valve body having a central bore and a plurality of ports in a surface thereof extending from said bore, hollow nipples resilient relative to said subplate extending from said ports exteriorly of said body, means attaching said valve body to said subplate manifold with said ports and openings being aligned whereby said nipples are received in said openings with the exterior surfaces of said nipples sealingly engaging the interior surfaces of said openings, and a valve member reciprocably received in said bore for selectively opening and closing said ports.

Claim 9

A valve assembly comprising a subplate manifold having a plurality of openings to a first surface thereof, a valve body having a central bore and a plurality of ports in a surface thereof extending from said bore, hollow nipples resilient relative to said subplate extending from said ports exteriorly of said body, means attaching said valve body to said subplate manifold with said ports and openings being aligned whereby said nipples are received in said openings with the exterior surfaces of said nipples sealingly engaging the interior surfaces of said openings, and a valve member reciprocably received in said bore for selectively opening and closing said ports.

Claim 10

The valve assembly of claim 7 wherein each of said openings has an annular groove therein, and including a radially, outwardly extending resilient flanges on each of said nipples, said annular grooves receiving said flanges when said nipples are received in said openings.

Claim 11

A valve comprising a valve body having an elongated central bore therein, axially spaced fluid pressure and emission ports opening into said bore, a reciprocating valve member received in said bore for selectively opening and closing said ports, a plurality of annular sealing means spaced axially of said bore and including radially, inwardly extending resilient annular flanges each received respectively in an annular groove in the wall of said bore, and an O-ring seal attached to each of said flanges and sealingly engaging said valve member.

Claim 12

A valve comprising a valve body having an elongated central bore therein, axially spaced fluid pressure and emission ports opening into said bore, a reciprocating valve member received in said bore for selectively opening and closing said ports, a plurality of annular sealing means spaced axially of said bore and including radially, inwardly extending resilient annular flanges each received respectively in an annular groove in the wall of said bore, and an O-ring seal attached to each of said flanges and sealingly engaging said valve member.

Claim 13

A valve assembly comprising a subplate manifold having a cavity with an open end, and having a plurality of openings to a first surface of said cavity, a unitary valve body of an elastomeric material received in said cavity and having a central bore and a plurality of ports in a surface thereof extending to said bore and being aligned with said openings in said subplate manifold, a valve member reciprocably received in said bore for selectively opening and closing said ports, first sealing means integrally formed on said valve body and surrounding said ports and in sealing engagement with said subplate around said openings, and second sealing means formed on the wall of said central bore and sealingly engaging said valve member, and A cover member attached to said subplate and closing said open end of said cavity and limiting the expansion of said body at said open end when said valve body is pressurized.

Claim 14

A valve assembly comprising a subplate manifold having a cavity with an open end, and having a plurality of openings to a first surface of said cavity, a unitary valve body of an elastomeric material received in said cavity and having a central bore and a plurality of ports in a surface thereof extending to said bore and being aligned with said openings in said subplate manifold, a valve member reciprocably received in said bore for selectively opening and closing said ports, first sealing means integrally formed on said valve body and surrounding said ports and in sealing engagement with said subplate around said openings, and second sealing means formed on the wall of said central bore and sealingly engaging said valve member, and A cover member attached to said subplate and closing said open end of said cavity and limiting the expansion of said body at said open end when said valve body is pressurized.
