Claims

[Scope of utility model registration request]

In a damper for a hydraulic and pneumatic suspension in which a hydraulic and pneumatic chamber is separated by a blocking wall and a rotary switching valve is provided in a communication path between the hydraulic chambers formed in the blocking wall, the rotary switching valve is mounted orthogonally to the communicating path. The cylindrical guide has a cylindrical guide installed in the hole and a cylindrical valve body rotatable within the cylindrical guide, and the cylindrical guide has an annular groove opening into one communicating path and a pair of opposing internal parts communicating with the annular groove. forming a through hole,
The cylindrical valve body has a connection hole that can be adapted to the internal through hole and an outlet in the end face in the direction of the rotational axis, and an outflow passage connected to the outlet is formed in the blocking wall and the cylindrical guide. A damper for hydraulic and pneumatic suspensions.
