Pressure fluctuation buffering mechanism and applicator

A pressure fluctuation buffering mechanism for buffering fluctuations in a paint flow, comprising:

• a buffer space comprising a first buffer zone forming member forming a first buffer zone in the buffer space, the first buffer zone having a plurality of first plates each arranged therein at first intervals, and a second buffer zone member forming a second buffer zone in the buffer space, the second buffer zone having a plurality of second plates each arranged therein at second intervals;
• an application member;
• and
• a paint flow space through which a paint flows, the paint flow space comprising a paint accommodation space having the paint accommodated therein, a paint feed space connecting the paint accommodation space and the application member and a paint feed core contained in the paint feed space for feeding the paint from the paint accommodation space to the application member,
• wherein the buffer space is connected to the application member via the paint flow space, the first buffer zone forming member includes a first connection channel for directly connecting between the first buffer zone and the paint feed core, the second buffer zone forming member includes a second connection channel for directly connecting between the second buffer zone and the paint feed core and the width of the first intervals is smaller than the width of the second intervals or the first buffer zone has a higher paint wettability than that of the second buffer zone to enable the paint between the first buffer zone and the paint flow space to flow more easily than the paint between the second buffer zone and the paint flow space.
