Abstract (en)
A trigger type liquid discharge device comprising a container, a pump unit having a cylinder and a piston, a discharge pipe (F) having a discharge aperture (405), and a trigger (102) for reciprocating the piston. Liquid drawn up from the container is discharged through the discharge aperture by movement of the piston to a stroke end. A liquid guide (403) is arranged in a liquid flow path (407) disposed upstream relative to the discharge aperture (405). The liquid guide (403) comprises a valve body (410) for closing the liquid flow path (407), a pressure bearing sleeve (411) formed integrally with the valve body (410), a guide sleeve (417) connecting the valve body (410) and the pressure bearing sleeve (411) through an opening (420). The guide sleeve (417) of the liquid guide (403) is inserted into the inside of a guide sleeve (418) of a spin element (404). The valve body (410) is urged by a spring (413) between the guide sleeve (417) and a guide sleeve (418) to close the liquid flow path (407). The pressure bearing sleeve (411) has a pressure bearing surface (414) facing the upstream side of the liquid flow path (407) for bearing the liquid pressure. An area of the said pressure bearing surface (414) is so selected that a force generated by a proper liquid discharge pressure that is applied to said pressure bearing surface (411) is greater than the sum of a resilient force of the spring member (413) and a force applied to the pressure bearing surface (414) and directed to the downstream side of the liquid flow path (407). <IMAGE>
