摘要： A scroll-type fluid apparatus includes a housing whose interior is divided by upper and lower partitioning walls into chambers one over another, i.e., a discharge chamber communicating with a discharge port, an inlet chamber communicating with an inlet port and a drive chamber accommodating therein a motor. A first scroll member is disposed in the inlet chamber and has a lower surface formed integral with a first spiral scroll vane. A second scroll member is disposed in the inlet chamber at a location below the first scroll member and has a lower surface provided with a rotatable shaft which is rotatably supported in the lower partitioning wall. The second scroll member is integrally provided on an upper surface thereof with a second spiral scroll vane which is in mesh with the first scroll vane to form a plurality of variable-volume chambers. An oil pump is provided in the discharge chamber for supplying lubricant to contacting parts of the first and second scroll members. The rotatable shaft of the second scroll member is provided on the outer periphery thereof with a labyrinth seal and at least one annular oil seal for preventing leakage of lubricating oil and vacuum from the inlet chamber toward the drive chamber.
