PUMP DEVICE
Document Type and Number:
Japanese Patent JP2003269375
Kind Code:
A
Abstract:
To provide a pump device allowing relatively rough processing accuracy and assembly of a transmission shaft, thereby manufacture is facilitated, a cost is largely reduced, and the device is usable in a wide temperature range up to a high temperature from a low temperature.
This pump device is constituted so that rotation of a motor 2 is transmitted to a pump 6 via the transmission shaft 4. The transmission shaft 4 is divided and formed into a plurality of pieces. Mutual end parts of the divided shafts 4a and 4b are coaxially and magnetically coupled in a noncontact state by a magnet coupling 11.
