摘要: The present invention provides a method and apparatus for detecting a status of a valve, the valve being connected to a fluid circuit. The method includes the steps of establishing an expected value of a characteristic of the fluid of the fluid circuit, determining an actual value of the fluid characteristic of the fluid circuit, and determining a valve status in response to the actual value, and the expected value.
