    摘要： A method of testing an inlet-outlet valve being part of a valve unit, such as an inlet-outlet normally open valve unit (1) for opening or closing for a fluid, such as liquid gas, is provided. The inlet-outlet valve can be brought into a closed position, which closes for a fluid passage, by supply of a pressurized control oil, and from the closed position the inlet-outlet valve can be brought into an open position, allowing a fluid passage, when the pressure of a supplied fluid exceeds a gas opening pressure for a given control oil pressure. For testing purpose, the supplied fluid is a test gas, such as Nitrogen. A method is provided for verifying that the inlet-outlet valve, when brought in the closed position by supply of pressurized control oil, stays closed without leaks when the pressure of the supplied test gas is below a gas opening pressure corresponding to the pressure of the supplied control oil. The test gas may be supplied at a pressure being not lower than 90% or 95% of the gas opening pressure corresponding to the pressure of the supplied control oil. The inlet-outlet valve may be provided with an outer valve body seal (14, 15, 16) and an inner valve piston seal (17, 18), and the method may further comprise verifying that the outer valve body seal and the piston seal are tight, when the inlet-outlet valve is in the normally open position without supply of pressurized control oil. A method is also provided for verifying that the inlet-outlet valve, when being in the closed position by supply of pressurized control oil, opens when the pressure of the supplied test gas exceeds the gas opening pressure corresponding to the pressure of the supplied control oil.

    摘要： Method of testing a gas injector valve for a combustion engine. The valve is placed in a holder (1) with a first chamber (2 )and a second chamber (3), the valve spraying nozzle (11) being placed in the first chamber (2), after which the valve in a closed condition is influenced by a test gas under pressure to control whether the valve seat and the valve gaskets (13a, 13b) are leak proof. This method makes it possible to indicate the position of a leak if any.

    摘要： A method of checking a deaerating valve for an injector valve. the injector valve with pistons and a top cover is placed in a holder and the deaerating valve is mounted in the top cover and control oil is supplied to the deaerating valve. The pressure of the control oil being increased so as to close the deaerating valve and control oil is accumulated in an accumulator, after which the control oil pressure slowly decreases until the deaerating valve opens, and the opening pressure is shown on a display. As a result, the opening pressure of the deaerating valve can be checked.

    摘要： Method of testing a gas shut-down valve for a combustion engine, by which method the valve is placed in a chamber of a holder 1 and the valve in closed condition is influenced by a non-burnable test gas under pressure to check whether the valve seat and the sealing ring 6 of the valve are close. Further the opening and closing functions of the valve are to be checked.
