Abstract: An air conditioning system for a vehicle including an integral valve block (32) having a liquid line bore (42) extending therethrough and a suction line bore (44) extending therethrough with a transverse by-pass passage (34). The by-pass check valve (38) of the first system of Figures 1 and 2 allows only one-way fluid flow through the by-pass passage (34) from the suction fluid line (22) to the liquid fluid line (20), whereas the by-pass check valve (40) of the second system of Figures 3 and 4 allows only one-way fluid flow through the by-pass passage (34) from the liquid fluid line (20) to the suction fluid line (22). Also integrated into the valve block (16) is a suction check valve (46) in the suction fluid line (22) for allowing one-way fluid flow from the evaporator (16) to the compressor (12).
