Abstract (en)

[origin: WO9506848A1] The invention relates to a hot and cold machine operating on a regenerative gas circuit process with two linearly movable pistons (8, 9) in a pressuretight housing (1) which together define a hot working volume (Vw) and one of which (8) limits a hot working volume (Vh) to which heat is applied and the other (9) limits a cold working volume (Vk), while the three working volumes (Vh, Vw, Vk) are interconnected via regenerators (Rh, Rk) and heat exchangers (Ww, Wk). In order to obtain a good heat input with small outside dimensions and sufficient pressure resistance, the hot working volume (Vh) is supplied with the heat via a convex partition (6) forming part of the pressuretight housing (1), with the curve symmetrical in rotation and lagged against the housing (1).
