Abstract:
With a first rotation angle (θ1) in the circumferential direction of a cylinder (121) of a piston (125) positioned at top dead center being 360 degrees, when the piston (125) is positioned at a third rotation angle (θ3) having the median of an angle range formed by a first rotation angle (θ1) and a second rotation angle (θ2), at which the pressure of a refrigerant in a compression chamber (133) reaches a maximum value, in a plane orthogonal to the axial direction of a rotary shaft (15), the center (O1) of the rotary shaft (15) is eccentrically disposed from the bore center (O2) of the cylinder (121) toward the position of the third angle (θ3) along a straight line (Le) connecting the bore center (O2) of the cylinder (121) with the position of the third angle (θ3) on the inner circumferential surface (137) of the cylinder (121) such that a gap (D) between the position of the third angle (θ3) on the inner peripheral surface (137) of the cylinder (121) and an outer peripheral surface (139) of the piston (125) becomes the smallest in the circumferential direction of the cylinder (121).
