Abstract

PURPOSE:To obviate a starting failure caused by strain, by truing up the direction made by opposite setting parts of a cylinder pressed in a closed case with the direction of magnetic attraction of a motor element's main winding, among rotary compression elements in a rotary compressor. CONSTITUTION:A cylinder 10 housing a rotor 12 has setting parts 8 and 9 for a closed case 2 at the outer surface part in its opposited diametral direction and it is pressed in the inner wall of the closed case 2 whereby secured thereto. On the other hand, a motor element 5 has both a main winding 3 and an auxiliary winding 4 but it is to be installed, as shown in illustration, by adjusting the direction of magnetic attraction produced out of the main winding 3 with the direction of said setting parts 8 and 9. With this, even when the magnetic attraction has acted, there produces no strain on the cylinder 10 at all and clearance between the rotor 12 and the cylinder 10 can be always kept in an optimum state so that a starting failure can be obviated.

When the electric element (5) and the rotary compression element (7) are press-fitted into the inner wall of the closed container (2), the main winding (3J
Cylinder 1 was simply determined arbitrarily by positioning, ignoring the direction of the magnetic attraction force that occurs when starting the cylinder.
The magnetic attraction force of 3J acts on the thin part of the main winding 101, causing distortion and the fitting dimensions with the roller lI4 to be incorrect, causing poor starting and eventually causing burnout problems. occured.
