<p>PURPOSE:To prevent a turning scroll from colliding with an inlet chamber side termination point of a fixed scroll by installing a recess in a lap nearby the fixed scroll inlet chamber side terminal point. CONSTITUTION:A recess is installed in a fixed scroll lap 11 in the vicinity of an inlet chamber terminal point 11a of a fixed scroll 4 with a circular or straight line. Length l of this recess is good enough as far as a turning radius or so, and a relief value m at the terminal point 11a is good to the extent of adding a clearance between a bearing and a crankshaft and another clearance between a boss part and the crankshaft at the alrgest. With this recess installed, a turning scroll 5 gradually comes into contact with the fixed scroll lap 11 without entailing any collision at the terminal point 11a, so that occurrence of damage and noise in both laps 11, 16 is kept back.</p> |
