Abstract: A safety device for a vehicle can include an impulse sensor configured to sense an impact to the vehicle and generate an impulse signal based on the impact, a compressor configured to compress refrigerant for a refrigeration cycle of the vehicle, and a safety valve connected to the compressor and configured to receive the impulse signal from the impulse sensor, and in response to the impulse signal exceeding a predetermined value, open the safety valve to place an inner space of the compressor in communication with an outside of the compressor for discharging the refrigerant outside the vehicle.

Abstract: Systems and techniques are disclosed to sense a temperature and a flow rate of oil in a compressor. A compressor includes: a casing; a frame on the casing; a fixed scroll on the frame; an orbiting scroll supported by the frame and defining a compression chamber while engaging the fixed scroll; and a crank shaft. The crank shaft transfers, to the orbiting scroll, a rotational force of a motor. The casing includes: a main housing including a refrigerant discharge passage and an oil passing passage; and a sub-housing including a refrigerant discharge port and an oil channel, which includes an oil reservoir, that each face the main housing. A sensor module attached to a sensor receptor in the sub-housing includes: a sensor housing covering the sensor receptor; and an oil sensor and a temperature sensor located on the sensor housing that each protrude towards the oil reservoir.
