Head depression type dispenser

摘要: A head depression type dispenser comprises a cylinder formed of an elastic material such as rubber. The is arranged between and cap, constructed to operate piston for sucking pressurizing liquid by axial deformation the upon movement head. When depressing force applied its removed after deformed, will return original shape own elasticity. In addition, sealing piece extends from into passage head, thereby closely contacting inner wall form secondary valve. becomes isolated when hydraulic pressure in exceeds elasticity piece, allowing flow compressed through passage, contacts lower than piece. Since can deform direction, it be sufficiently high pressure.
