Summary:To provide a rotary drive part that can minimize an amount of protrusion of a rotary drive unit to the outside and prevent unintended inflow of a refrigerant into a compression area, and a rotary heat pump.SOLUTION: Provided are: a rotary drive part 10 in which an inner wall surface of a rotary housing 15 of the rotary drive part 10 includes at least one compression region, where a continuous groove 15A is formed in the compression region between an adjacent forward-most expansion region on a forward side of the compression region at the forward-most position in a rotation direction of a rotor 13 and an adjacent rear-most expansion region on the rear side of the compression region at the rear-most position in the rotation direction of the rotor 13; and a rotary heat pump having the rotary drive part.SELECTED DRAWING: Figure 4 【課題】ロータリー駆動部の外側へのはみ出しを可及的に少なくすると共に、意図しない圧縮領域への冷媒の流入が防止可能なロータリー駆動部とロータリー型ヒートポンプを提供すること。【解決手段】ロータリー駆動部10のロータリーハウジング15の内壁面には、少なくとも一つの圧縮領域を含み、この圧縮領域においてロータ13の回転方向における最前方位置の圧縮領域の前方側で隣接する最前方膨張領域と、ロータ13の回転方向における最後方位置の圧縮領域の後方側で隣接する最後方膨張領域との間で連続する凹溝15Aが形成されていることを特徴とするロータリー駆動部10と、これを有するロータリー型ヒートポンプである。【選択図】図4
