A working mechanism (1) in a heat engine and, if the working mechanism (1) is substantially arranged for reversed functions, in a heat pump is described, the working mechanism (1) including at least one variable-volume chamber (150) defined by a displacement device (200) and provided with at least one working- fluid inlet (400), and at least one heat exchanger (300, 300a, 300b) which is in thermal contact with the variable-volume chamber (150) via at least one heat- exchanger surface (301), the at least one heat exchanger (300, 300a, 300b) completely or partially surrounding or being surrounded by the variable-volume chamber (150), and the displacement device (200) being provided with means (203, 210, 211) arranged to provide fluid communication between each and all of the at least one heat exchanger (300, 300a, 300b), the working- fluid inlet (400) and the variable-volume chamber (150) in every one of the positions of the displacement device (200) within the variable-volume chamber (150). A method for heat exchange in a heat engine and, when the method is substantially reversed, in a heat pump is described as well, the heat engine including a working- fluid circuit, a thermo fluid circuit and at least one working mechanism (1). |
