摘要
An oil replacement assembly includes a housing in which a plurality of circuits and gauges are incorporated therein. An inner one-way valve is arranged between a first connecting port and a third connecting port of a 9-way valve, while a second inner one-way valve is arranged between a second connecting port and a fourth connecting port of the 9-way valve. An eighth connecting port of said 9-way valve is connected to the first connecting port, and is further connected to a dual-3-way valve. A fifth connecting port and a second connecting port are connected to another port of the dual-3-way valve, while another port of the dual-3-way valve is connected to a sixth connecting port of the 9-way valve. Wherein when the first connecting port and the second connecting port are incorrectly connected, contaminated oil received in the second connecting port will be redirected back to the first connecting port.
