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 high pressure pump comprising: a plunger that is adapted to reciprocate;a cylinder that is configured into a bottomed tubular form and includes: an inner peripheral wall that slidably guides the plunger;an inner bottom wall that is continuous from the inner peripheral wall, wherein the inner bottom wall is configured into a generally conical form, which has an increasing diameter toward the plunger;an outer peripheral wall; andan intake hole and a discharge hole, which communicate between the inner peripheral wall and the outer peripheral wall; anda pump housing that includes: a cylinder receiving hole that includes an inner peripheral wall, into which the cylinder is inserted, wherein the inner peripheral wall of the cylinder receiving hole contacts the outer peripheral wall of the cylinder;an intake passage that is communicated with the intake hole; and a discharge passage that is communicated with the discharge hole, wherein a pressurizing chamber is formed by the inner peripheral wall and the inner bottom wall of the cylinder and a distal end outer wall of the plunger upon installation of the cylinder and the plunger into the cylinder receiving hole, whereinthe pump housing further includes: a first housing that is engaged with a bottom portion of the outer peripheral wall of the cylinder, which is located on a radially outer side of the inner bottom wall of the cylinder; anda second housing that is engaged with a tubular portion of the outer peripheral wall of the cylinder, which is located on a radially outer side of the inner peripheral wall of the cylinder;the cylinder has a limiting portion that limits movement of the cylinder toward the bottom portion of the cylinder relative to the housing when a pressure of the pressurizing chamber is increased; andthe second housing is placed between and contact with the first housing and the limiting portion of the cylinder. 2. The high pressure pump according to claim 1, further comprising: an intake valve that is installed in the intake passage of the pump housing and meters fuel to be drawn in to the pressurizing chamber; anda discharge valve that limits backflow of fuel, which is discharged from the pressurizing chamber into the discharge passage in the pump housing. 3. The high pressure pump according to claim 1, wherein a portion of the outer peripheral wall of the cylinder, which is axially located between the inner bottom wall and an outer bottom wall of the cylinder, is fitted to the inner peripheral wall of the cylinder receiving hole. 4. A high pressure pump comprising: a plunger that is adapted to reciprocate;a cylinder that is formed into a bottomed tubular form and includes a bottom portion and a tubular portion, wherein: the bottom portion closes one end of the tubular portion;the plunger is slidably supported by an inner wall of the tubular portion;a pressurizing chamber is formed by an upper end of the plunger, the inner wall of the tubular portion and an inner bottom wall of the bottom portion; andan intake hole and a discharge hole are formed through at least one of the bottom portion and the tubular portion to radially communicate between an inside and an outside of the pressurizing chamber; anda housing that is engaged with an outer wall of the bottom portion and an outer wall of the tubular portion, wherein:the housing includes: a first housing that is engaged with the outer wall of the bottom portion of the cylinder; anda second housing that is engaged with the outer wall of the tubular portion of the cylinder;the cylinder has a limiting portion that limits movement of the cylinder toward the bottom portion of the cylinder relative to the housing when a pressure of the pressurizing chamber is increased; andthe second housing is placed between and contacts with the first housing and the limiting portion of the cylinder. 5. The high pressure pump according to claim 4, wherein the limiting portions a projection, which is formed in the outer wall of the tubular portion and projects radially outward from the outer wall of the tubular portion. 6. The high pressure pump according to claim 5, wherein the projection is formed in the outer wall of the tubular portion at a location within a slidable range of the plunger along the inner wall of the tubular portion of the cylinder. 7. The high pressure pump according to claim 5, wherein the projection extends to an opening end of the tubular portion of the cylinder, which is opposite from the bottom portion. 8. The high pressure pump according to claim 5, wherein the projection is configured into an annular form and extends all around the outer wall of the tubular portion of the cylinder in a circumferential direction of the tubular portion. 9. The high pressure pump according to claim 4, wherein the limiting portion is a fixing member, which is fitted into a recess that is formed in the outer wall of the tubular portion of the cylinder. 10. The high pressure pump according to claim 9, wherein the fixing member is configured into a generally C-shaped form and extends along the outer wall of the tubular portion of the cylinder. 11. The high pressure pump according to claim 4, wherein the housing includes: an intermediate support member that supports the cylinder on a radially outer side of the cylinder and has: one end portion, which contacts an outer wall of the first housing located on a side opposite from the bottom portion of the cylinder; andthe other end portion, which contacts an outer wall of the second housing located on a side where the bottom portion of the cylinder is placed.
