The invention relates to an apparatus for use in a liquid circulation system of the kind comprising a primary circulatory circuit provided with a circulation pump and having a primary forward flow and a primary return flow, as well as a secondary circulatory circuit with a secondary forward flow and a secondary return flow, said primary and secondary forward and return flow being connected to the apparatus, and the liquid circulating in the primary and secondary circulatory circuits being of substantially the same composition. The apparatus comprises two positively interconnected displacement machines (A, B), of which one (A) receives the primary forward flow (P.F.) and delivers the secondary forward flow (S.F.), whilst the other (B) receives the secondary return flow (S.R.) and delivers the primary return flow (P.R.), the volumetric effects for the displacement machines (A, B) being mutually attuned so as to ensure that the volume flows in the primary forward flow, the secondary forward flow, the secondary return flow and the primary return flow are substantially equal. This makes it possible to operate with different pressures in the primary and the secondary circulatory circuits, respectively, without the necessity of using a heat exchanger between them. The invention also comprises control facilities for protecting against loss of liquid from the primary circuit to the secondary circuit in the case of leakage in the latter.

[ What is claimed is:] [1.] Apparatus for use in a liquid circulation system, which liquid system comprises a liquid, a primary circulatory circuit provided with a circulation pump for the liquid and having a primary forward flow and a primary return flow, as well as a secondary circulatory circuit
[ What is claimed is:] [1.] Apparatus for use in a liquid circulation system, which liquid system comprises a liquid, a primary circulatory circuit provided with a circulation pump for the liquid and having a primary forward flow and a primary return flow, as well as a secondary circulatory circuit provided with a utilization device for the liquid having a secondary forward flow to the utilization device and a secondary return flow from the utilization device, the apparatus comprising:a primary inlet which receives liquid from the primary forward flow,a primary outlet which delivers liquid to the primary return flow,a secondary inlet which receives liquid from the secondary return flow,a secondary outlet which delivers liquid to the secondary forward flow,two positively interconnected displacement machines (A, B), of which one displacement machine (A) receives the liquid of the primary forward flow (F.F.) from the primary inlet and delivers the liquid of the secondary forward flow (S.F.) to the secondary outlet, and of which the other displacement machine (B) receives the liquid of the secondary return flow (S.R.) from the secondary inlet and delivers the liquid of the primary return flow (P.R.) to the primary outlet, anda flow equalization means whereby the volumetric effects of the displacement machines (A, B) are attuned to each other in a manner to ensure that the volume flows in the primary forward flow, the secondary forward flow, the secondary return flow and the primary return flow are substantially equal.
