The invention relates to heat pump circuit elements. It relates to a circuit element comprising two pressed metal sheets which are welded at 14 so that they define cavities containing different components of the circuit such as a four-way cock, a silencer, a pressure reducer, a valve, a dehydrating cartridge, etc. Those elements which must be fixed in a sealed manner are fixed by the welding of a filler material, once the two pressed members have been seam- or spot-welded together.
