<p>PURPOSE:To prevent the idling of a roller and the shifted abrasion by devising such a roller as the relative wave plate type compressor will be constant over the entire length of the roller. CONSTITUTION:A wave plate 100 arranged on the outer circumference of a shaft 300 and a roller 200 for contacting with the wave plate 100 to drive a piston 305, are provided. The roller 200 is formed conical to have such cross-section as will decrease toward the shaft 300. The conical shape is formed to have such a cross-section reducing rate as the ridges of the roller 200 will match on the central axis of the shaft 300.</p> |
