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.

A fluid pump has a cylinder supporting a plunger and a pump housing formed with dissimilar metals. A pressing mechanism presses the cylinder and the pump housing relative to each other so that a pressurizing chamber is sealed through a pressing surface between the pump housing and the cylinder. The number of seal points can be reduce, and a reduction in reliability can be eliminated while realizing a reduction in weight of the pump housing and a reduction in cost due to increase in cutting capability, by using a soft material such as an aluminum alloy fo...

The invention claimed is: 1. A fluid pump comprising: a pump housing, a cylinder comprising a longitudinal bore extending from one cylinder end through the cylinder to an opposite cylinder end, and a plunger, supported by the cylinder to reciprocate, which pressurizes fluid in a pressurizing chamber formed between said cylinder and said pump housing and which has an end arranged so as to move beyond said one cylinder end of the cylinder to protrude into the pressurizing chamber, wherein said cylinder element is pressed against said pump housing, forming at least one metal seal that delimits said pressurizing chamber, and said metal seal is provided in an outer portion of said cylinder element and spaced from ends of the cylinder. 2. The fluid pump according to claim 1, further comprising: a pressing mechanism which presses said pump housing and said cylinder relatively so that both may be not in contact except at the metal seal, wherein said pump housing and said cylinder form said metal seal on a plane intersecting a shift direction of said plunger. 3. A fluid pump comprising: a first member in which a concavity is formed, a second member, which defines a cylindrical body forming said concavity as a fluid pressurizing chamber, a plunger, supported in a hole extending, in the second member, from one cylindrical body end through the cylindrical body to an opposite cylindrical body end so as to reciprocate, which pressurizes the fluid in said fluid pressurizing chamber and which has an end arranged so as to move beyond an said cylindrical body end to protrude into the pressurizing chamber, a seal part formed at a pressure-contact location of said first and second members, provided in an outer portion of said second member and spaced from both the pressurizing chamber and ends of said second member, and a pressing mechanism by which said first and second members are pressed together so that the seal part delimits the pressurizing chamber. 4. A fluid pump comprising: a pump housing, a cylinder comprising a longitudinal bore extending from one cylinder end through the cylinder to an opposite cylinder end, a pressurizing element that pressurizes the fluid in a pressurizing chamber formed between said cylinder and said pump housing and that has an end arranged so as to move beyond said one cylinder end to protrude into the pressurizing chamber, a seal part formed at a pressure-contact location between said pump housing and said cylinder, which seals the pressurizing chamber formed between said cylinder and said pump housing, and a pressing mechanism by which said pump housing and said cylinder element are relatively pressed together to install them so that the seal part delimits the pressurizing chamber. 5. The fluid pump according to claim 1, wherein a portion of said cylinder, which extends to a side of said pressurizing chamber from said metal seal, is free from seal pressure of said metal seal. 6. The fluid pump according to claim 1, further comprising: a pressing mechanism that presses said pump housing and said cylinder relatively to form said metal seal, wherein said metal seal is formed by pressing said pump housing and said cylinder together in a plane intersecting in a shift direction of said plunger. 7. The fluid pump according to claim 3, wherein the seal part is formed by pressing said first and second members together in a plane intersecting a direction in which said plunger is reciprocated, and the pressing mechanism presses said first and second members relatively at the plane. 8. The fluid pump according to claim 7, wherein said first member is a metallic pump housing having said concavity, said second member is a metallic tube body having a hardness higher than said metallic pump housing, which forms said concavity as a fluid pressurizing chamber by assembly with said metallic pump housing, said plunger is supported by said metallic tube body so as to be able to reciprocate in an axial direction, said seal part is a metal seal formed by pressure-contact of said metallic pump housing and said metallic tube body on said plane, and said pressing mechanism presses said metallic pump housing and said metallic tube body relatively to form said metal seal. 9. The fluid pump according to claim 3, wherein said first member is made of aluminum alloy, and said second member is made of iron-system alloys having a hardness higher than that of the aluminum alloy. 10. The fluid pump according to claim 3, wherein gaps that allow thermal deformation differences caused by the thermal expansion differences between said first and second members are provided between the inner periphery of said first member and the outer periphery of the second member. 11. The fluid pump according to claim 4, wherein said seal part is formed by pressing said pump housing and said cylinder on a plane intersecting in a shift direction of said pressurizing element. 12. The fluid pump according to claim 4, wherein said seal part is a metal-contact seal provided between said pump housing and said cylinder, in an outer periphery of said cylinder, and spaced from the pressurizing chamber. 13. The fluid pump according to claim 4, wherein an inner periphery of said pump housing and an outer periphery of said cylinder are not in contact except at the seal part. 14. The fluid pump according to claim 1, wherein said fluid pump pressurizes gasoline from 5 to 20 megaPascal. 15. The fluid pump according to claim 4, wherein said fluid pump pressurizes gasoline from 5 to 20 megaPascal. 16. The fluid pump according to claim 5, wherein said fluid pump pressurizes gasoline from 5 to 20 megaPascal. 17. A fluid pump comprising: a pump housing in which a concavity is formed, a cylinder assembled with said pump housing, which forms said concavity as a fluid pressurizing chamber, and a plunger, supported by said cylinder to reciprocate in a bore extending from one cylinder end through the cylinder to an opposite cylinder end, which pressurizes fluid in said pressurizing chamber and which has an end arranged so as to move beyond said one end to protrude into the pressurizing chamber, wherein fuel inhaled into said pressurizing chamber by reciprocation of said plunger is pressurized and discharged from said pressurizing chamber, wherein said cylinder is pressed against said pump housing so that said pressurizing chamber is formed by a seal provided by metal contact between said pump housing and said cylinder, which metal contact delimits said pressurizing chamber, and said seal is provided in an outer periphery of said cylinder and spaced from a pressurizing chamber side of said cylinder, and wherein said plunger goes into and back from said pressurizing chamber. 18. The fluid pump according to claim 17, wherein said pump housing and said cylinder are assembled so that they may be in a non-contact state at an outer periphery face of a pressurizing chamber side of said seal. 19. The fluid pump according to claim 17, wherein an annular gap is provided between opposing surfaces of said pump housing and said cylinder in a radial direction and on a pressurizing chamber side of the seal.
