Summary:PURPOSE: A laminal flow passage is blocked by a spring force to give a constant pressure, and a piston having a spherical end is provided to reduce pressure loss and fluid resistance. CONSTITUTION: An injection nozzle comprises a piston valve body(140) slidably moving in a cylinder(113). A valve head(10) contacting with the piston valve body is formed in a spherical shape. A plurality of grooves(25) is formed in outer surface of the piston valve body to introduce water from a first cylinder chamber(142) to a second cylinder chamber(150) along the outer circumference of the piston valve body. Filter nicks(40) in vertical direction are formed in a filter cap(35) to reduce pressure loss of water and fluid resistance.
