    • The present dental handpiece has a burr sleeve, a head section, an air supply passage for introducing compressed air into the head section for driving the burr sleeve, and an air discharge passage for discharging the compressed air. The air supply passage includes a through hole axially extending through the rear terminal part of the handpiece, and a tubular pressure regulating member and an air supply tube connected in series between the through hole and the head section. The pressure regulating member has an aperture for allowing communication with the air discharge passage, and an annular valve body arranged axially slidably for opening/closing the aperture. When the pressure of compressed air passing through the air supply passage exceeds a predetermined level, the valve body is slid to open the aperture to discharge the compressed air for regulating the pressure of the compressed air to be supplied to the burr sleeve.
    • 本牙科手机具有毛刺套筒,头部,用于将压缩空气引入用于驱动毛刺套筒的头部的空气供给通道,以及用于排出压缩空气的排气通道。 空气供给通道包括轴向延伸穿过手持件的后端子部分的通孔以及串联连接在通孔和头部之间的管状压力调节构件和空气供给管。 压力调节构件具有用于允许与排气通道连通的孔,以及可轴向滑动地设置以打开/关闭孔的环形阀体。 当通过供气通道的压缩空气的压力超过预定水平时,阀体滑动以打开孔,以排出压缩空气,以调节供应到毛刺套筒的压缩空气的压力。
