Definitions
- the catches for the depressions or projections forming prism-shaped catches in the area of the control slide are arranged on both sides of the control groove for the tappet on the control slide. It is expedient if the body of the catch is designed as a stepped piston with a hollow interior, which is partially used to receive its load spring.
