| 摘要 |
<p>The invention relates to a reversible pneumatic machine with rotary piston which may operate as pneumatic motor or as a compressor. The machine claimed by the invention consists of stator (1) having an inner surface of pericycloid shape with two lobes, wherein, a rotary piston (2) having a hypocycloid shape with three flanks (a, b, c) rotates on a shaft (3) with eccentric, being entrained by an inner gear, some apexes (A, B, C) and flanks (a, b, c) of the piston (2) delimit in the stator (1) several chambers (I, II, III and IV) which have to be sealed between them, the sealing between the apexes (A, B, C) of piston (2) and the wall of stator (1) being ensured by some segment-type lamellar parts (4) mounted in some channels (5) machined in the apexes (A, B, C) of the piston (2) and positioned by some leaf springs (6), the sealing between the flanks (a, b, c) of the piston (2) of the wall of stator (1) being ensured by two movable sealing parts (7) mounted inside some T-shaped channels (8) machined in a small axle of the stator (1) and positioned by some leaf springs (9) with characteristics higher than the first leaf springs (6).</p> |
