摘要： A fluid compressor in which the drive shaft is arranged in a casing including a fluid suction chamber and a fluid discharge chamber concentrically formed therein, with an eccentric end thereof projected from an open end of the casing. Secured to the open end of the casing is a cylinder housing formed integrally with cylinders cruciformly intersecting with each other. Placed in the cylinders are pistons which define therein a recess in which the eccentric end of the drive shaft is fitted. A flange-like bearing retainer chamber is secured to the inner peripheral wall of the open end of the casing which has a hub bulged in the cylinder housing. A needle bearing is mounted in the hub with a portion thereof located in the cylinder housing and supports a portion of the drive shaft adjacent the eccentric end thereof.

摘要： A useful sealing device which serves to fluidtightly seal a clearance between a cylindrical member and a cylindrical bore into which said cylindrical member is to be fitted. The sealing device comprises an annular endless resilient seal ring made of a resilient sheet-like material and having an inner diameter smaller than an outer diameter of a seal fitting portion on the cylindrical member. One of the opposite surfaces of the resilient seal ring is tightly fitted around the fitting portion of the cylindrical member in a facing relation to each other, whereas the other surface of the same is faced to the sealing surface of the cylindrical bore and at least a part thereof is placed in resilient contact with the sealing surface.
