PURPOSE:To prevent breakage of a cooler compressor by installing an intake pressure answering apparatus which detects the negative pressure generated on the intake pipe side of a prime mover and a installing timer which connects a load onto the prime mover with a prescribed time lag. CONSTITUTION:An intake pressure answering apparatus A is interconnected with the intake pipe 5 of a prime mover. The top edge of the rod 20 of a timer T is set, keeping a prescribed distance for a pushing rod 10. When the suction pressure is sharply reduced by the sharp acceleration, the pushing rod 10 is attracted onto an electromagnet 22, and a switch 39 is closed to release a compressor B from a prime mover. When the suction pressure reaches a prescribed value, a switch 40 is opened after the lapse of a prescribed time by the operation of a switch 37 and a timer T. Therefore, connection between the prime mover and the compressor B is performed intermittently in the minimum range, so the prime mover is revolved smoothly, and breakage of compressor is prevented. |
