The invention relates to a device (1) for transferring heat from a gaseous working medium (M2) to a heat-exchanger medium (M3) by compressing the gaseous working medium (M2), wherein the device (1) comprises: an operating line (AL), wherein the volume (V) enclosed by the operating line (AL) is divided into at least two sections, namely a first (AL-V1) and a second section (AL-V2), wherein the first section (AL-V1) is set up to hold a pressure-transfer medium (M1) and the second section (AL-V2) is set up to hold and discharge the gaseous working medium (M2), wherein at least one inlet and outlet valve (2) is provided for holding and discharging the gaseous working medium (M2), wherein a first volume delimited by the first section (AL-V1) is separated from a second volume delimited by the second section (AL-V2) by a first separating layer (T12) that can be displaced within the operating line (AL), wherein the first separating layer (T12) is arranged in such a way that pressure differences between the first (AL-V1) and second sections (AL-V2) of the operating line (AL) are equalized by a displacement of the first separating layer (T12) in the operating line (AL) and an accompanying change in the proportion between the first volume and the second volume is equalized, and comprising a heat-exchanger line (WL) to hold the heat-exchanger medium (M3), wherein the heat-exchanger line (WL) is coupled to the first section (AL-V1) of the operating line (AL) to bring about pressure equalization.

The gas propulsion thrust device comprises a cone-shaped propulsion element with a rigid concave internal surface and a second convex external surface. The propulsion element is submerged in gas and aligned with a high-frequency linear actuator, which causes its reciprocal motion along the longitudinal axis, generating thrust. The device includes a thrust chamber that supports the actuator and surrounds the propulsion element, maintaining a consistent gap between the propulsion element and the chamber to direct gas from the second side to the first side. The chamber tapers around the propulsion element, and a gas directing cap is configured to direct gas around the second side towards the first side. Propulsion element is rigid and its shape remains unchanged during the operation. The reciprocal motion creates a gas pressure differential across the propulsion element, generating thrust by propelling gas away from the propulsion element in the opposite direction of propulsion. The device offers efficient and controlled thrust generation.
