A DEPRESSION HEAD FOR PUMP MECHANISM |
摘要 |
A pump push-down head with improved sealing of a nozzle and excellent liquid cut-off property. The head comprises a fitting cylindrical member (3) with a slidable cylinder (9) communicating with a stem (2), a main body (4) having a valve chamber (A) with a nozzle (12) opened at its tip above a fitting cylinder (11) fitted to the outer circumference of the slidable cylinder, an d arranged so as to be pushed down with respect to the fitting cylindrical member, a valve member (5) which closes the nozzle in a forwardly urged stat e and defines a flow passage leading to the nozzle from a communication port (19) communicating with a cylinder, and a lever member (6) of special configuration which is interlocked with the valve member to open the valve when the head is pushed down. The push-down resistance of the main body against the stem is set to be smaller than the push-down resistance of the stem itself.
