PCT No. PCT/SE81/00259 Sec. 371 Date May 25, 1982 Sec. 102(e) Date May 25, 1982 PCT Filed Sep. 14, 1981 PCT Pub. No. WO82/01217 PCT Pub. Date Apr. 15, 1982.A cam apparatus is disclosed which has a cam profile which is varied by axially moving the drive shaft. Two cam members on the shaft form a cam lobe. Guide bodies mounted in the shaft engage slanted grooves on the inner walls of the cam members, so that axially moving the drive shaft turns the cam members. In one embodiment, the cam members may meet in the area of the cam lobe when the cam lobe is narrow, and may be spaced apart when it is wide, or they may overlap when it is narrow and provide a continuous profile when it is wide. |
