연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A cartridge valve and valve manifold assembly comprising: a valve manifold having at least one valve receptacle for receiving and seating a cartridge valve;said valve receptacle having an inner valve nose with a first passage therethrough and a second passage outside of said valve nose leading from said valve receptacle;said cartridge valve having a valve body with a distal end sealingly seatable in said valve receptacle and having an actuator device therein;a movable plunger being moveable by said actuator device from an open position unseated away from said valve nose to provide open fluid communication between said first and second passage and to a closed position seated with said valve nose to close off said first passage from said second passage;said valve receptacle and said cartridge valve having a positive releasable lock device to releasably lock said cartridge into said valve receptacle; andwherein the releasable positive lock device is in the form of a flexible tab having a base end integrally formed on said valve body of said cartridge valve and axially extending away from said distal end and then axially back toward said valve body and facing radially outward and a receiving groove on the valve manifold open radially inward to receive said flexible tab when in a normal radially outward position; andsaid flexible tab being flexible radially inward to disengage from said groove and allow said cartridge valve to be installed in and pulled out of said valve receptacle. 2. A cartridge valve and manifold assembly as defined in claim 1 further comprising: said valve body having a central aperture to slidably receive said plunger that extends therethrough; andsaid valve body having a port communicating between said valve receptacle and said valve body to provide transfer of fluid to and from said valve body with said valve receptacle to prevent vacuum lock condition of said plunger that prevents movement of said plunger. 3. A cartridge valve and valve manifold assembly as defined in claim 1 further comprising: said valve manifold being made of a molded plastic material with the valve nose integrally and simultaneously formed as a unitary section of said valve manifold. 4. A cartridge valve and valve manifold assembly as defined in claim 3 further comprising: said movable plunger having a stop shoulder to abut said valve body to retain said movable plunger with said cartridge valve. 5. A cartridge valve and valve manifold assembly as defined in claim 1 further comprising: said movable plunger having a stop shoulder to abut said valve body to retain said movable plunger with said cartridge valve. 6. A cartridge valve and valve manifold assembly as defined in claim 1 further comprising: said second passage extending axially in the same direction as said first passage and having an outlet facing an axial end of said cartridge valve. 7. A cartridge valve and valve manifold assembly as defined in claim 6 further comprising: said second passage being substantially annular and axially surrounding said first passage. 8. A cartridge valve and manifold assembly comprising: a valve manifold having at least one valve receptacle for receiving and seating a cartridge valve;said valve receptacle having an inner valve nose with a first passage therethrough and a second passage outside of said valve nose leading from said valve receptacle;said cartridge valve having a valve body sealingly seatable in said valve receptacle and having an actuator device therein;a movable plunger being moveable by said actuator device from an open position unseated away from said valve nose to provide open fluid communication between said first and second passage and to a closed position seated with said valve nose to close off said first passage from said second passage;said valve receptacle and said cartridge valve having a positive releasable lock device to releasably lock said cartridge into said valve receptacle;wherein the releasable positive lock device is in the form of a flexible tab on one of the valve manifold and cartridge valve and a receiving groove on the other of the cartridge valve and manifold;said valve body having a central aperture to slidably receive said plunger that extends therethrough;said valve body having a port communicating between said valve receptacle and said valve body to provide transfer of fluid to and from said valve body with said receptacle to prevent vacuum lock condition of said plunger that prevents movement of said plunger; andsaid port being a longitudinally extending groove in said central aperture. 9. A noseless cartridge valve assembly for seating in a valve manifold, said cartridge valve assembly comprising: a valve body with a distal end seatable in said valve manifold;an actuation device for actuating a moveable plunger between an open and closed position;said moveable plunger having a first seal thereon and extending into a chamber in the valve body for seating on a nose in a valve receptacle when in the closed position;a locking tab assembly having a base end integrally formed on said valve body and axially extending away from said distal end and then axially back toward said valve body and radially extending from said valve body for engagement to a valve manifold;said locking tab assembly has a flexible tab on said cartridge valve facing radially outward and a receiving groove on the valve manifold open radially inward to receive said flexible tab when in a normal radially outward position;said flexible tab being flexible radially inward to disengage from said groove and allow said cartridge valve to be repeatedly installed in and repeatedly pulled out of said valve receptacle; anda proximate end of said valve body constructed to seat a second seal member for being sealingly connectable to said valve receptacle. 10. A noseless cartridge valve assembly as defined in claim 9 further comprising: said movable plunger having a stop shoulder to abut said valve body to retain said movable plunger with said cartridge valve. 11. A noseless cartridge valve assembly as defined in claim 10 further comprising: said valve body having a central aperture to slidably receive said plunger that extends therethrough;said valve body having a port communicating between said chamber and said cartridge valve assembly to provide transfer of fluid to and from said chamber with said cartridge valve assembly to prevent vacuum lock condition of said plunger that prevents movement of said plunger. 12. A noseless cartridge valve assembly as defined in claim 9 further comprising: said valve body having a valve mounting sleeve co-axially surrounding said movable plunger with said movable plunger extending into said sleeve when moved to a closed position. 13. A noseless cartridge valve assembly comprising: a valve body;an actuation device for actuating a moveable plunger between an open and closed position;said moveable plunger having a first seal thereon and extending into a chamber in the outer valve body for seating on a nose in a valve receptacle when in the closed position;a locking tab assembly extending from said valve body for engagement to a valve manifold;a proximate end of said valve body constructed to seat a second seal member for being sealingly connectable to said valve receptacle;said movable plunger having a stop shoulder to abut said valve body to retain said movable plunger with said cartridge valve;said valve body having a central aperture to slidably receive said plunger that extends therethrough;said valve body having a port communicating between said chamber and said cartridge valve assembly to provide transfer of fluid to and from said chamber with said cartridge valve assembly to prevent vacuum lock condition of said plunger that prevents movement of said plunger; andsaid port being a longitudinally extending groove in said central aperture.
