<p>In a refrigerating system comprising a reciprocating compressor (1), a condensor (2), an expansion means (3), an evaporator (5), a temperature-sensitive control element (6) for on/off control of the compressor, a refrigerant-pressure-dependent valve (4) is used for shutting off the flow of refrigerant between the condensor and the evaporator when the compressor is off and for allowing the flow of refrigerant between the condensor and the evaporator when the compressor is on. The valve (4) comprises a pressure-sensitive means (9) which is movable under the influence of the condensor outlet pressure which prevails at one side of the pressure-sensitive means, whilst the pressure at the other side of the pressure-sensitive means depends on the saturation pressure of a liquid in a circuit which includes a bulb (15) arranged at a location where it is exposed to the influence of ambient temperature.</p> |
