A fluid compressor comprises a cylinder block, a driving shaft rotatably mounted in the cylinder block by means of thrust bearings and radial bearings, an inclined disk rigidly secured to the driving shaft, pistons slidably disposed in cylinder bores formed in the cylinder block, and shoes for operably connecting the inclined disk to the pistons, which are reciprocally moved in the cylinder bores when the inclined disk is rotated to pressurize gaseous fluid for cooling. In order to accommodate the inclined disk, the cylinder block has a housing, which is provided with recesses or grooves on the opposite axial end surfaces to catch the lubrication oil flowing along the inner wall of the housing. Oil ports or passages are also provided for introducing the oil from the recesses or grooves to the radial bearings. Sliding bearings may be used as the radial bearings. Such a sliding bearing may be provided with an oil guide groove or ball indents on the inner peripheral wall thereof.

An inclined disk type compressor comprising: a cylinder block; a driving shaft rotatably mounted in said cylinder block by means of thrust bearings and radial bearings; a disk rigidly secured to said driving shaft at a certain inclined angle with respect to the axis of said driving shaft; said cylinder block having a chamber for accommodating said inclined disk so as to allow the rotation of the latter; said cylinder block having cylinder bores which are arranged in parallel to the axis of said driving shaft; the opposite ends of each said cylinder bore being communicated with a suction passage and a discharge passage via a suction valve and a discharge valve, respectively; compressor pistons slidingly disposed in said cylinder bores so that gaseous fluid containing lubrication oil is compressed in said cylinder bores by said pistons; shoe means for operatively connecting the peripheral portion of said inclined disk to said compressor pistons so as to cause the reciprocal movement of said compressor pistons upon the rotation of said inclined disk; said radial bearings being sliding radial bearings arranged at positions apart from said chamber which is communicated with said suction passage so that at least a part of the gaseous fluid containing lubrication oil is introduced into said chamber and then introduced into said cylinder bores after having been passed through said chamber; said chamber being provided on the opposite axial internal end walls with grooves for receiving lubrication oil flowing down along internal end surfaces; and said radial bearings being communicated with said grooves through oil passages which are bored in the cylinder block so as to be open to said grooves and introduce the lubrication oil to said radial bearings.
