ABSTRACT:
The present invention relates to a programmer control device.
This device comprises a rotary cam block 5 intended to be driven step by step by an advancing device comprising three advancing pawls 21, 22, 23 mounted on an oscillating support. The first pawl 21 can directly actuate step by step the first toothed ring 31 integral with the first part 1 of the cam block 5. The second pawl 22 interacts under the action of an elastic means with the smooth periphery 25 of a cylindrical extension 26 forming part of the second part 2 of the cam block 5. It likewise interacts, via orifices 30 passing completely through this extension 26, with a second toothed ring 32 integral with the first part 1. The third pawl 23 interacts under the action of an elastic means with a third toothed ring 33 integral with the inner periphery of a rate reduction collar 3 mounted rotatably inside the second part 2 of the cam block 5. It likewise interacts, via orifices 40 passing completely through the collar 3, with a fourth toothed ring 34 integral with the second part 2 of the cam block 5.
The present control device can be used particularly in programmers intended for controlling clothes washing machines.
