An arrangement wherein fluid pressure passageways opening into inner chambers of a cylindrical housing of a valve device, are formed between abutting faces of two axially aligned cylindrical portions comprising the housing. The opening or passageway between the abutting faces is formed by complementarily engaging saw-like teeth formed around the annular abutting faces of the two housing portions. This arrangement provides a smoother surface over which the sealing gasket on a valve member must ride, thus resulting in less wear and tear on the gasket.

Arrangement of fluid pressure passageways in cylinder devices

A manually operable actuation pin for operatively engaging the solenoid armature of an electromagnetic valve device is provided to permit manual emergency or auxiliary control of the armature. The actuation pin is designed to permit locking in its actuated position by rotation thereof. The operating end of the actuation pin is arranged with an inner segment, an intermediate segment and an outer segment defined by annular grooves therebetween adapted to facilitate separation of the respective segments. One or more of these segments may be removed to obtain a specific operating characteristic in accordance with which the actuating pin is to be operated.
