Claims

[Claims for Utility Model Registration] An air limit switch comprising a valve body for opening and closing an air flow passage provided in a housing and a driving means for the valve body, the air limit switch having a cylinder inside the housing. The housing is mounted with a gap provided between the outer circumferential surface of the cylinder and the inner circumferential surface of the housing, and an air flow passage with a double inner and outer structure is formed that communicates in a U-turn shape from the inner space of the cylinder to the above-mentioned gap, and the housing An annular air outflow hole is provided on the end face of the air flow path, and the annular air outflow hole communicates with one end of the void portion, which is the downstream end of the air flow path, and the center portion of the air outflow hole is provided with an annular air outflow hole that communicates with one end of the air gap, which is the downstream end of the air flow path. An air limit switch characterized in that an air inflow hole is provided that communicates with one end of the space, and the valve body is disposed in an internal space of the cylinder that constitutes a part of the air flow path.
