passivaattorivasun
Passivaattorivasun is a Finnish term describing a valve or actuator output stage driven by a passive actuator. It denotes devices that translate stored or environment-provided energy into motion or regulation without requiring sustained external power input, distinguishing them from active actuators such as electric motors or hydraulic cylinders.
Principle and mechanisms typically involve the use of preloaded springs that release energy when a threshold
Applications and context include safety devices, thermostats, mechanical timers, vibration dampers, and systems where electric power
Advantages of passivaattorivasun concepts are simplicity, high reliability, low maintenance, and quiet operation. Limitations include restricted
