Abstract

PURPOSE: To prevent the blowing-through of oil in the tangential direction even if laps imperfectly contact while keeping seal effect by labyrinth effect by minute structure for maintaining oil even if oil is insufficient, by mounting said minute structure to the flanks of the laps.
CONSTITUTION: In this scroll type fluid machine, space 13 is formed by a side- wall and an end surface 11 of a lap 3 of a fixed scroll 1, the side-walls and end surfaces 12 of the laps 4 of a turning scroll 2, the surfaces 9 of an end plate 7 of the fixed scroll 1, the surfaces 10 of an end plate 8 of the turning scroll 2 and a line 14 that the laps 3, 4 contact, and gas sucked from a suction hole 5 is compressed at the space and discharged from a discharge hole 6. A large number of small, dotted, concave portions 15 are installed to said line 14 that the laps contact. Thus, seal effect can properly be obtained all the time because oil films on the flanks of the laps that are once damp with oil are continually held by means of the concave portions 15 even at virtual contact line locations 14' in the case when contact is imperfect.
