  • Patent number: 5984654
    Abstract: A fluid reaction device (10) is provided having a rotor (90) with vanes (92) pivotably connected thereto. The device (10) includes an entrance (30) for elevated pressure fluid and an outlet (40) for discharge of the fluid after contacting the rotor (90). The elevated pressure fluid passes from the entrance (30) into a high pressure area. The high pressure area is in contact with inlet ports (74) accessing a cylinder (70) within the device (10). The cylinder (70) supports the rotor (90) with a rotational axis (M) of the rotor (90) off center with respect to a central axis (N) of the cylinder (72). The elevated pressure fluid causes the rotor (90) and an attached output shaft (97) to rotate. The rotor (90) includes a trunk (24) with a plurality of posts (93) extending therefrom and with vanes (92) connected to the posts (93) through hinges (94). The vanes (92) can pivot from a first position collapsed against the trunk (24) to a second position spaced away from the trunk (24).

  • Patent number: 5697773

The device 10 includes an entrance 30 for elevated pressure fluid and an outlet 40 for discharge of the fluid after contacting the rotor 90. The elevated pressure fluid passes from the entrance 30, into a high pressure chamber 80. The high pressure chamber 80 is in contact with inlet ports 74 accessing a cylinder 72 within the device 10. The cylinder 72 supports the rotor 90 with a rotational axis M of the rotor 90 off center with respect to a central axis N of the cylinder 72. The elevated pressure fluid causes the rotor 90 and an attached output shaft 97 to rotate. The rotor 90 includes a trunk 24 with a plurality of posts 93 extending therefrom and with vanes 92 connected to the posts 93 through hinges 94. The vanes 92 can pivot from a first position collapsed against the trunk 24 to a second position spaced away from the trunk 24.

  • Patent number: 5667383
    Abstract: A disposable dental prophylaxis handpiece 10 is provided having a rotor 90 with vanes 92 pivotably connected thereto. The handpiece 10 includes an entrance 30 for elevated pressure fluid and an outlet 40 for discharge of the fluid after contacting the rotor 90. The elevated pressure fluid passes from the entrance 30, into a high pressure chamber 80. The high pressure chamber 80 is in contact with inlet ports 74 accessing a cylinder 72 within the handpiece 10. The cylinder 72 supports the rotor 90 with a rotational axis M of the rotor 90 off center with respect to a central axis N of the cylinder 72. The elevated pressure fluid causes the rotor 90 and an attached output shaft 97 to rotate. This in turn pauses a prophylaxis cup 160, coupled to the output shaft 97, to rotate. The rotor 90 includes a trunk 24 with a plurality of posts 93 extending therefrom and with vanes 92 connected to the posts 93 through hinges 94.
