Refrigerant relief device
First Claim
1. A refrigerant relief device for releasing refrigerant filled in a refrigeration cycle for an automotive air conditioner into the atmosphere, comprising:
- a thin film disposed in a manner blocking a refrigerant inlet passage connected to the refrigeration cycle; and
a thin film-breaking section for breaking the thin film to thereby release the refrigerant introduced from the refrigeration cycle into the refrigerant inlet passage into the atmosphere.

Abstract
To provide a refrigerant relief device which releases refrigerant in a refrigeration cycle to the outside of a vehicle compartment, when the refrigerant releases into the vehicle compartment, or when there is a fear that the refrigerant releases into the vehicle compartment. A metal thin film is welded in advance to a body connected to piping of a refrigeration cycle such that it blocks a refrigerant inlet passage. When leakage of refrigerant into a vehicle compartment or collision of an automotive vehicle is detected, pulse current is applied to a coil of a solenoid, whereby a movable core is attracted to a fixed core. This causes a piercing rod fixed to the movable core to pierce the metal thin film with its pointed tip to make a hole through the metal thin film. When application of the pulse current is stopped, the piercing rod is returned to the standby position by a spring, so that the refrigerant is released to the outside of the vehicle compartment by passing through a conduit via the opened hole.
