  • Well reamer
    Patent number: 5184687
    Abstract: The well reamer comprises a sub for attaching it to the drive means, a hollow housing with a central channel and radial openings in its side wall, projectable rolling cutters with shanks, mounted in the radial openings of the housing, and a mechanism for projecting the rolling cutters, including a piston and a member for locking the rolling cutters in their operating positions. The annular piston is connected with the housing for joint rotation therewith, and is regidly connected with the sub. The wall of the piston has radial passages made therein, establishing communication between its central channel and so annular space defined between the walls of the piston and of the housing. The member for locking the rolling cutters is accommodated with a clearance in the central channels of the piston and of the housing, and has an annular shoulder. The central channel of the piston defines a seat for engagement with the annular shoulder of the locking member.
