Abstract: The invention relates to a heating/cooling system for a vehicle, in particular for an electric or hybrid vehicle, comprising components, in particular a compressor (10), a condenser (11), and expansion device (12), and an evaporator (13) which are fluidically connected together in order to form a fluid circuit. The invention is characterized by a holding element (14) with a wall structure (15) which has at least one through-opening (16). At least two components are arranged on opposite sides of the wall structure (15) and are mechanically connected to the wall structure (15), wherein the two components are directly fluidically connected together by the through-opening (16) in order to form a fluid passage. The invention additionally relates to a holding element for such a heating/cooling system.

Abstract: The invention relates to a displacement machine according to the spiral principle, in particular a scroll compressor or scroll expander, with a high-pressure chamber, a low-pressure chamber and an orbiting displacement spiral, which engages in a counter-spiral such that chambers are formed between the displacement spiral and the counter-spiral for receiving a working medium, wherein a counter-pressure chamber is formed between the low-pressure chamber and the displacement spiral. According to the invention a pressure regulating device which is fluidically connected to the counter-pressure chamber sets a pressure difference between the counter-pressure chamber and the low-pressure chamber by means of a set value specified by the computing unit.

Abstract: The invention relates to a positive-displacement machine according to the spiral principle, particularly a scroll compressor, having a high-pressure region, which comprises a high-pressure chamber, furthermore having a low-pressure chamber and an orbiting positive-displacement spiral, which engages into a counterpart spiral in such a manner that compression chambers are formed between the positive-displacement spiral and the counterpart spiral, in order to accommodate a working medium, wherein a counterpart-pressure chamber is constructed between the low-pressure chamber and the positive-displacement spiral.
