Description

Dual Capacity Sealed Refrigeration Compressor With Reversible Motor

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 밀봉한 냉동 압축기 일종의 단면도, 제2도는 제1도의 Ⅱ-Ⅱ선을 따라 취한 상세한 단면도, 제3도는 제2도의 Ⅲ-Ⅲ선을 따라 취한 단편적인 단면도, 제4도는 모터가 한 방향이나 다른 방향으로 교대로 크랭크축을 구동할 때 제2도와 제3도의 기구를 가지고 구해진 행정길이 변화를 도시하는 개략도. 제5도는 본 발명의 다른 실시예의 단면도, 제6도는 제5도의 Ⅵ-Ⅵ선을 취한 단편적인 단면도.1 is a cross-sectional view of a sealed refrigeration compressor, FIG. 2 is a detailed cross-sectional view taken along line II-II of FIG. 1, FIG. 3 is a fragmentary cross-sectional view taken along line III-III of FIG. 2, and FIG. Schematic diagram showing the change in stroke length obtained with the mechanisms of FIG. 2 and FIG. 3 when driving the crankshaft alternately in different directions. FIG. 5 is a cross-sectional view of another embodiment of the present invention, and FIG. 6 is a fragmentary cross-sectional view taken along line VI-VI of FIG.

Claims

A rotary crankshaft with a crankpin eccentric with respect to the crankshaft, a reversible motor for driving the crankshaft in the direction of rotation, respectively, and a piston connected to the crankshaft through connecting rods having end bearings circulating around the crankplate In the above-described cylinder and a double-capacity sealed refrigeration compressor that constitutes a piston stroke adjusting device for automatically changing the stroke length of the piston in the reverse direction of the crankshaft, respectively, the piston stroke adjusting device is supported to rotate on the crank pin. Crank in such a way as to produce an eccentric ring during the rotation of the crankshaft to move with the eccentric ring, journaled to the end bearing of the connecting rod, and without any angular arrangement between the crankpin and the eccentric ring. Inserted between pin and eccentric ring, crankshaft rotation Limited eccentricity-exchange between the crankpin and the eccentric ring while the initial part entails reversal in each direction. Double capacity sealed refrigeration compressor with reversible motors constituting a valid device during the initial part of the crankshaft rotation
