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.

초록

A torque converter check valve has a valve element movable between a closed position and an open position by applying hydraulic pressure to a portion of the valve element and by applying a resilient force by a resilient element acting on another portion of the valve element. A spacer element is provided to act on the valve element and limit movement of the valve element in the direction in which the resilient element is compressed to reduce wear on the resilient element during operation of the torque converter check valve.

1. A method of converting an automotive transmission, said method comprising the steps of: providing a torque converter check valve having a valve element movable within a housing having at least one planar side between a fully closed position and a fully opened position as a result of hydraulic pressure applied to said valve element to move said valve element in a first direction, and a resilient element applying a resilient force on said valve element to move said valve element in a second direction, said fully opened position and said fully closed position being separated by a predetermined distance, converting said automotive transmission by limiting the movement of said valve element to prevent said valve element from moving into said fully opened position for reducing wear on said resilient element by mounting a separate spacer element directly on said valve element such that said spacer element is conjointly movable with said valve element;arranging said resilient element to be in direct contact with said at least one planar side of said housing; andarranging said valve element and said spacer element such that when said valve element is moved from said fully closed position in a direction towards said fully opened position, said spacer element abuts against said at least one planar side of said housing before said valve element moves said predetermined distance so that said valve element is not in said fully opened position when said valve element is moved a maximum distance in a direction towards said fully opened position. 2. The method in accordance with claim 1, further including the step of arranging said spacer element to limit movement of the valve element in a direction in which said resilient element is compressed. 3. The method in accordance with claim 2, further including the step of applying the hydraulic pressure to the valve element so as to move the valve element in the direction which compresses the resilient element. 4. The method in accordance with claim 1, wherein said hydraulic pressure acts on said valve element to move said valve element in said first direction from a closed position towards an opened position, and said resilient element acts on said valve element in said second direction to move said valve element from an opened position towards a closed position, the steps of said method further including: arranging said spacer element to limit the distance which said valve element moves between a fully closed position and a fully open position. 5. The method in accordance with claim 1, further including the step of: arranging said resilient element to apply said resilient force on the inside of said valve element. 6. The method in accordance with claim 1, further including the step of: applying said hydraulic pressure to the outside of said valve element. 7. The method in accordance with claim 1, wherein said resilient element is a spring. 8. In a torque converter check valve for an automotive transmission, said torque converter check valve including a valve element, a housing having at least one planar side for said valve element, a resilient element acting on said valve element to move said valve element in said housing in a first direction, said valve element being movable in said housing in a second direction upon the application of hydraulic pressure to said valve element, said valve element being movable in said housing between a fully opened position and a fully closed position, said fully opened position and said fully closed position being separated by a predetermined distance, said resilient element being expanded when said valve element moves in said first direction, and said resilient element being compressed when said valve element moves in said second direction, the improvement comprising a separate spacer element directly mounted on said valve element and conjointly movable with said valve element for limiting movement of said valve element to prevent said valve element from moving into said fully opened position; said valve element and said spacer element being arranged such that when said valve element is moved from said fully closed position in a direction towards said fully opened position, said spacer element abuts against said at least one planar side of said housing before said valve element moves said predetermined distance into said fully opened position so that said valve element is not in said fully opened position when said valve element is moved a maximum distance in a direction towards said fully opened position; said resilient element arranged to be in direct contact with said at least one planar side of said housing. 9. The torque converter check valve in accordance with claim 8, wherein the spacer element is arranged to limit movement of the valve element in the second direction to limit the compression of the resilient element when the valve element is moved in the second direction. 10. The torque converter check valve in accordance with claim 9, wherein said spacer element is arranged to limit the distance that said valve element moves in said second direction from a closed position into an opened position. 11. The torque converter check valve in accordance with claim 10, wherein said spacer element is arranged to cooperate with the inside of said valve element. 12. The torque converter check valve in accordance with claim 11, wherein said resilient element is arranged to act on the inside of said valve element, and said spacer element is arranged inside of said resilient element. 13. The torque converter check valve as claimed in claim 8, wherein movement of the valve element in the first direction closes the torque converter check valve. 14. The torque converter check valve as claimed in claim 8, wherein movement of the valve element in the second direction opens the torque converter check valve. 15. The torque converter check valve as claimed in claim 8, wherein the valve element is arranged to receive said applied hydraulic pressure on the outside of the valve element for moving the valve element in said second direction for opening the torque converter check valve. 16.
