Title:
AIR SUPPLYING DEVICE
Document Type and Number:
Japanese Patent JPH04358713
Kind Code:
A
Abstract:
PURPOSE:To manufacture a noise reduction tank easily and form the tank in a compact size. CONSTITUTION:An air supplying device is provided with the air pump 1 of a reciprocating motion type which has a discharging port 1a for discharging compressed air, and an bag 2 having a leading port 2a for leading the compressed air. Also, the device is provided with a noise reduction tank 3 formed in a prescribed inner volume, wherein a leading port 3a is provided for leading the compressed air, and a flow passage 4 connected to the air bag 2 branching in nearly right direction from the leading port 3a of the noise reduction tank 3, wherein the air pump 1 is connected to the noise reduction tank 3. Since the noise reduction tank 3 having one inlet/outlet of air is used for suppressing pulsation noise of the compressed air supplied intermittently from the air pump 1 of the reciprocating motion type into the air bag 2, it is possible to manufacture the noise reduction tank 3 easily, and also economize space for piping to the noise reduction tank 3.
