Method for operating a metering device, and metering device

摘要

The invention relates to a method for operating a dispensing device (10, 110) for releasing an agent from the dispensing device (10, 110) in defined manner into a surrounding environment (15) of the dispensing device (10, 110), the dispensing device (10, 110) comprising: a reservoir unit (16, 116) for accommodating an agent to be dispensed and a valve unit (17, 117) for defined opening and closing of a valve passage (26, 29, 34, 126, 129, 134) from the reservoir unit (16, 116) into the surrounding environment (15) of the dispensing device (10, 110), opening and closing of the valve passage (26, 29, 34, 126, 129, 134) proceeding as a function of an ambient temperature profile of the dispensing device (10, 110) and the valve passage (26, 29, 34, 126, 129, 134) being opened when the ambient temperature falls and the ambient temperature is above a first and/or second defined minimum temperature.

主权项

1. A dispensing device (10, 110), for releasing an agent from the dispensing device (10, 110) in defined manner into a surrounding environment (15) of the dispensing device (10, 110), the dispensing device comprising:
a.) a reservoir unit (16, 116), for accommodating the agent to be dispensed, b.) a valve unit (17, 117) for defined opening and closing of a valve passage (26, 29, 34, 126, 129, 134) from the reservoir unit into the surrounding environment (15) of the dispensing device (10, 110), the valve unit (17, 117) comprising at least one first valve means (21, 121) which may be changed over between an unobstructed state and a closed state, and c.) a control unit for controlling the valve unit (17, 117), the control unit comprising at least one thermosensitive actuator (39, 139) which is capable of bringing about a changeover of the at least one first valve means (21, 121) as a function of an ambient temperature profile, and a friction clutch, formed by a friction disk (38) interacting with at least one thermosensitive actuator (39, 139) wherein the friction disk (38) is in frictional connection with the at least one first valve means (21,121).
