Abstract

종래 ABS시스템에 사용되었던 솔레노이드밸브가 갖는 록지방기능을 보다 효율적으로 수행하기 위하여 통상의 고압차단 솔레노이드밸브에 봉상 압력차단봉(6)이 탄성부재(7)의 중앙을 관통하여 하단부(6a)가 (★스캔)형의 요크(3)의 중앙슬립홈(3a)에 삽입되며, 상단부(6b)가 밸브실(14)에 길게 연장되어 밸브시트(8)에 밀착되며, 에어갭(12)의 위치를 코일(2)의 중앙부 근처에 까지 배치되도록 하는 것을 특징으로 한느 ABS용 고압차단 솔레이노이드 밸브를 첨가한 것을 개발하였음.In order to perform the lock fat function of the solenoid valve used in the conventional ABS system more efficiently, the rod-shaped pressure blocking rod 6 penetrates the center of the elastic member 7 to the normal high pressure blocking solenoid valve. Inserted into the center slip groove 3a of the yoke 3 of the scan type, the upper end 6b extends long in the valve chamber 14 to be in close contact with the valve seat 8, and the position of the air gap 12 Was developed to add a high pressure blocking solenoid valve for ABS, characterized in that it is arranged to be near the center of the coil (2).

Description
