Abstract

Improvements introduced in cooling systems including a compressor, a condenser and an evaporator connected in a refrigeration circuit, a valve for controlling the flow of refrigerant from said evaporator to said compressor, said valve including means forming a chamber having an inlet orifice connected to the exit orifice of said evaporator, and an outlet orifice connected to the inlet of said compressor, a valve seat surrounding said inlet orifice, a valve element having a limb that can enter in contact with said seat and able to move towards said seat and in the opposite direction to control the flow of fluid through said opening, said means including said chamber forming a movable wall attached to said element and subjected to the fluid pressure that exists inside said chamber, a wall that can be displaced by sliding r a portion of said valve element, said wall including an inlet opening, said portion of said movable valve member through said inlet opening when said valve member is spaced from said inlet hole to block said inlet opening. Inlet and so that it can move away from said inlet opening when said valve element approaches and is in contact with said seat, means joining said inlet opening with the high pressure side of said compressor, and means for moving said valve element towards the seat of said valve and in the opposite direction.
