Valve e.g. inlet valve, arrangement for petrol engine, has annular groove, and valve including closure body with upper side facing valve opening and covered by cap that is slidably and axially guided relative to shaft

摘要

The arrangement has a valve (3) including a closure body (5) with an upper side (7) facing a valve opening (6). The closure body is attached to a shaft (4). The upper side is covered by a cap (8) that is slidably and axially guided relative to the shaft. The cap is guided against force of a spring (9) i.e. pressure spring, and/or a pneumatically loaded piston. The spring surrounds the shaft and is supported between the upper side and an annular shoulder (12) that is fixed to the cap. An annular groove (23) supports the spring.
