Title:

PUMP UNIT AND METHOD OF MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2016/133024

Kind Code:

A1

Abstract:

The objective of the present invention is to provide a pump unit and a method of manufacturing the same with which it is possible to reduce the number of components and simplify the manufacturing process. A pump unit (1) is provided with: a pump (2) including a piezoelectric element (4) and a discharging mechanism (5) which discharges a fluid in response to the operation of the piezoelectric element (4); and a valve mechanism (3) which is attached to the pump (2). The discharging mechanism (5) and the valve mechanism (3) are each formed by diffusion bonding together a plurality of metal plates (22) to (37) in a state in which the plurality of metal plates (22) to (37) have been stacked on one another in a preset stacking direction, and the discharging mechanism (5) and the valve mechanism (3) are further fixed to one another by diffusion bonding.
