Embodiment Construction

[0061] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. will refer to Figures 1 to 23B A rotary cylinder device to be incorporated in a compressor will be described as an embodiment of the present invention. The rotary cylinder device can convert the reciprocating motion of the piston in the cylinder and the rotary motion of the shaft to each other.

[0062] exist figure 1 Among them, a shaft (input / output shaft) 4 is rotatably held in a main body case 3 composed of a first case 1 and a second case 2 . The first housing 1 and the second housing 2 are integrated by bolts 3 a respectively provided at four corners of the main body housing 3 . Such as image 3 As shown, in the main body housing 3, the eccentric cylindrical body 6 that can rotate around the first crankshaft 5 and constitutes the composite piston assembly P (see figure 2 ) and the first piston unit 7 and the second piston unit 8, whi...

Abstract

In the rotary type cylinder device, a first crank shaft is revolved around a shaft and a composite piston assembly is revolved around the first crank shaft in a state where first rotational mass balance relating to first and second piston units around second virtual crank shafts, second rotational mass balance relating to the composite piston assembly around the first crank shaft and third rotational mass balance relating to the first crank shaft and the composite piston assembly around the shaft are uniformly produced by only first and second balance weights which are attached to end parts of the first crank shaft. Therefore, first and second piston units, which are attached to the second cylindrical sections, are linearly reciprocally moved in radial directions of a circular orbit of second virtual crank shafts, which has radius of 2r, with relatively revolving around the shaft.

Description

technical field [0001] The present invention relates to a rotary cylinder device capable of mutually converting the reciprocating motion of the piston in the cylinder and the rotary motion of the shaft, and more particularly to a rotary cylinder that can be applied to internal combustion engines, compressors, vacuum pumps, hydraulic rotary machines, etc. device. Background technique [0002] In each of the internal combustion engine, compressor, vacuum pump, hydraulic rotary machine, etc., a different type of drive mechanism is employed. For example, a reciprocating drive mechanism that repeatedly sucks in and discharges fluid by the reciprocating motion of a piston unit connected to a crankshaft, a drive mechanism that repeatedly sucks in and discharges fluid by rotating a movable scroll relative to a fixed scroll, etc. A scroll type drive mechanism, a rotary drive mechanism that repeatedly sucks and discharges fluid through the rotational motion of a drum (see JP-A-2004-1...
