摘要： A manually operated spray device for spraying a liquid in a vessel comprises a cylinder member which includes an upper air cylinder and a lower liquid cylinder, an air piston slidably fitted in the air cylinder, and a suction pipe connected to the liquid cylinder within the vessel toward the bottom thereof. An actuator member is urged upwards and vertically movable relative to the cylinder member; and includes a hollow stem protruding upwards from the liquid cylinder and fitted at its center portion with the air piston, a press head fitted onto the upper portion of the stem, a nozzle hole opening at the side surface of the press head, and first and second passages merging with each other on the upstream side of the nozzle hole. The first passage is communicated with the air chamber on one side of the air piston, and the second passage is communicated with the liquid cylinder through the interior of the stem. By depressing the actuator member and displacing the air piston within the air cylinder, the air in the air chamber is ejected from the nozzle hole while a vacuum pressure is applied to the interior of the second passage so that the liquid in the vessel is sprayed from the nozzle hole as a mixture with the ejected air.

摘要： A spray unit that is attached to an opening at a neck portion of a container for spraying a liquid material in the container, including: a cylinder unit composed of a large-diameter air cylinder and a small-diameter liquid cylinder having a valve hole and an operating member. The operating member is composed of a large-diameter cylindrical piston, a stem having a check valve, and a press-down head having a spray nozzle hole. The liquid is to be sprayed when the operating member is pressed down. When the operating member is pressed down, a liquid flow-out path and an air ejecting path come together via a small gap inside the spray nozzle hole. The spray unit further includes a flow rate control valve is composed of a valve seat provided at an upper face of a valve hole of the liquid cylinder and a valve body arranged above the valve seat to be seated on or released from the valve seat. At least one of the valve seat and the valve body is provided with a small flow path that is not closed even when the valve body sits on the valve seat and that always communicates the interior of the container with the interior of the liquid cylinder, and the flow rate control valve is provided with a large flow path that is opened when the valve body is released from the valve seat and closed when the valve body sits on the valve seat. The sectional area of the small flow path is smaller than an open area of the valve hole of the air cylinder and that of the valve hole of the check valve provided inside the stem. The combination overcomes the delay in ejecting the liquid.
摘要翻译：一种喷雾装置，其安装在容器颈部的开口处，用于将液体材料喷射在容器中，包括：气缸单元，其由大直径气缸和具有阀孔的小直径液缸组成，操作员操作构件由大径圆柱形活塞，具有止回阀的杆和具有喷嘴孔的下压头构成。当操作构件被按下时，喷射液体。当操作构件被按压时，液体流出路径和空气喷射路径通过喷嘴孔内部的小间隙聚集在一起。喷射单元还包括流量控制阀，其由设置在液筒的阀孔的上表面处的阀座和设置在阀座上方的阀体组成，以安置在阀座上或从阀座释放。阀座和阀体中的至少一个设置有即使当阀体位于阀座上并且总是将容器的内部与液筒的内部连通时也不闭合的小流动路径，以及流量控制阀设置有当阀体从阀座释放时打开的大流路，并且当阀体位于阀座上时关闭。小流路的截面积小于气缸的阀孔的开口面积，以及设置在阀杆内的止回阀的阀孔的截面积。该组合克服了喷射液体的延迟。
