    • 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, and 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 state 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.

    • A dispenser in which an operation load of a plunger is stable and the contents of the dispenser do not leak out after pressing operation is stopped. The dispenser has a syringe body (1) having a space in which the contents are placed and also having a pouring nozzle attached to the forward end of the syringe body, the plunger (2) slid, by pressing force applied to it, in the syringe body (1) to pour out the contents in the space (m) from the tip of the pouring nozzle, and an O-ring (3) placed in an annular groove (2c) formed in a forward end section of the plunger (2) and slidable on the inner wall surface of the syringe body (1). The annular groove (2c) is formed as a partitioned recess having a bottom wall flat over it. A projection or a groove (4) is formed in a side wall of the annular groove (2c), and the projection or the groove (4) guides back suction of the contents by causing, by restoring force of the O-ring (3), the plunger (2) to slide in the direction opposite to the push-in direction of the plunger (2).
    • 在停止压制操作之后,其中柱塞的操作负载稳定并且分配器的内容物不会泄漏的分配器。 分配器具有注射器主体(1),其具有放置内容物的空间,并且还具有附接到注射器主体的前端的倾倒嘴,柱塞(2)通过施加到其上的按压力而滑动 注射器主体(1)从倾倒嘴的前端倾倒在空间(m)中的内容物,以及置于形成在柱塞的前端部分中的环形槽(2c)中的O形环(3) 2)并且可以在注射器主体(1)的内壁表面上滑动。 环形槽(2c)形成为在其上具有平坦的底壁的分隔凹部。 在环状槽(2c)的侧壁形成有突起或槽(4),突起或槽(4)通过使O形环(3)的恢复力 ),柱塞(2)沿与柱塞(2)的推入方向相反的方向滑动。

    • A pressure accumulator-type liquid spraying device comprises a piston that is arranged in a cylinder; a piston guide that is disposed in and through a passage that penetrates through the piston in a direction along the axis of the piston, opens and closes the passage by the contact with and separation from the piston, and forms a space region for the suction and pressurization of liquid in cooperation with the cylinder and the piston; a check valve that opens a suction port of the cylinder when the liquid is sucked; and a hollow stem that is fitted slidably on the outside of the piston, with a liquid-tight state being kept, and engaged with an end of the piston guide. A first elastic member presses the piston guide against the piston to keep the passage of the piston in a closed state. A second elastic member presses the piston against the piston guide to adjust the spraying pressure of the content. The piston is positioned by a stopper, arranged in the cylinder, before the liquid is sprayed so that the contact surface pressure between the piston and the piston guide is increased and the passage is kept in a closed state. There is formed an annular recessed portion along an outer edge of a piston end portion with which the stopper comes into contact.
    • 蓄压式液体喷射装置包括设置在气缸中的活塞; 活塞引导件设置在穿过活塞的通道中并沿着沿着活塞的轴线的方向穿过活塞,通过与活塞的接触和分离而打开和关闭通道,并形成用于抽吸的空间区域, 与气缸和活塞协调加压液体; 止回阀,其在吸入液体时打开气缸的吸入口; 以及空心杆,其可滑动地装配在活塞的外部,其中保持液密状态并与活塞导向件的端部接合。 第一弹性构件将活塞引导件压靠在活塞上以保持活塞通过处于关闭状态。 第二弹性构件将活塞压靠在活塞引导件上以调节内容物的喷射压力。 在喷射液体之前,通过设置在气缸中的止动件定位活塞,使得活塞和活塞导向件之间的接触表面压力增加并且通道保持在关闭状态。 沿着活塞端部的外边缘形成有环形凹部,止动件与该活塞端部接触。
