Abstract:
A water discharge device having a housing that has inside a columnar space, a core
that is movable in the columnar space while splitting the space into first and
second pressure chambers and has inside an in-core flow path, a water discharge
tube body that communicates with the in-core flow path and reaches the outside
of the housing, a first water inlet opening that introduces fluid into the first
pressure chamber, a second water inlet opening that introduces the fluid into
the second pressure chamber, a first introduction opening that introduces the
fluid from the first pressure chamber into the in-core flow, a second introduction
opening that introduces the fluid from the second pressure chamber into the in-core
flow path, a valve body that changes the degree of opening of the first and second
introduction openings, and control means that inverts the relationship of the
high-low degree of opening of the first and second introduction openings. A compact
and simple structure of the water discharge device enables repetitive linear
