Abstract
An application head includes a storage-side valve, a discharge-side valve and a plunger. The storage-side valve slides in a space in communication with an intermediate liquid passage between the storage-side valve and the discharge-side valve and changes the volume of liquid in the intermediate liquid passage. Each of the storage-side valve and the discharge-side valve has a column-shaped part, includes a through-hole penetrating between outer circumferential surfaces of the column-shaped part, and is rotatable at least within a predetermined angular range around a center axis of the column-shaped part. Each of the through-holes of the storage-side valve and the discharge-side valve communicates with liquid passages on both sides at a predetermined rotational position and does not communicate with the liquid passage on both sides at other rotational positions outside the angular range.
