<p>The ejector (3) has a nozzle (4) with an inlet (10) for the liquid refrigerant, and a suction chamber (13) with an inlet (15) for the gas refrigerant. A passage section of the nozzle is modified by a movable valve element (18) i.e. valve needle. A spring (20) acts on the valve element, and is arranged in downstream of the valve element. The element is arranged in the upstream of the nozzle. The passage section of the nozzle is in the order of 0.1 square millimeters to 0.3 square millimeters when the element is closed, and is in order of 3 millimeters when the element is open to the maximum. The valve element is open when the pressure in the range of 100 to 140 bars is applied to the liquid refrigerant inlet.</p> |
