Where is the exhaust valve located on the BMW X5?

[EliLynn]

The exhaust valve of the BMW X5 is located on the valve cover. Introduction to the exhaust valve: The exhaust valve, also known as the oil separator or pressure control valve, is installed between the compressor outlet and the condenser inlet. Through separation, it improves the heat transfer efficiency of the condenser and evaporator. Working principle of the exhaust valve: The high-pressure gas from the compressor enters the exhaust valve and then flows through the guide vanes in a spiral motion. The centrifugal force and gravity separate the lubricating oil from the working gas, which flows down along the inner wall of the cylinder. The working gas is then discharged from the exhaust valve through the central pipe via multiple baffles. The separated lubricating oil accumulates at the bottom of the oil separator and can be periodically drained or automatically returned to the compressor's crankcase using a float valve.
