The sleeve and drive shaft are mounted in a housing (31) having an arresting means (22) at one end thereof for fixing the apparatus in an opening (24') of the compressor casing at an angle. The apparatus is provided with a thrust piece (34) biased by a coil spring against the sleeve (24). A nut (33) screwed over a tubular extension (32) is used to adjust the preload on the coil spring to thereby adjust the contact pressure of the friction wheel on the rotor surface. A square-head pin-type extension (18) of the drive shaft extends through a handle (12') provided with a flange (17). A crank apparatus (Figure 1A) provided with a crank (41), a fitting (40) having a square-shaped socket adapted to accommodate the extension (18) and a casing (44) is secured toPage: Previous 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 NextLast modified: November 3, 2007
