  • Method and device for testing solenoid valves
    Patent number: 9759760
    Abstract: A device for testing a solenoid valve includes: a voltage generator for applying a short pulse of voltage, which is not long enough to open the solenoid valve, to the windings of the solenoid valve; a current meter configured for measuring the current flowing through the windings of the solenoid valve; and an analysis device which is configured for analysing the current measured by the current meter for detecting a potential fault of the solenoid valve.
    Type: Grant

  • Apparatus and method for recovering refrigerant through a double conduit connection
    Patent number: 9574809
    Abstract: An apparatus for transferring a fluid from and/or to a system, e.g., an air conditioning system, includes a main compartment having at least one pumping device for pumping the fluid from/to the system, an interface module having at least one gauge which is configured for displaying the pressure of the fluid, and a fluid connection fluidly connecting the gauge to the main compartment. The fluid connection is formed in a double conduit design in order to prevent any leakage of the fluid from the fluid connection.
