摘要： A valve assembly for dispensing a measured quantity of a gelatinous semisolid material into a receptacle comprises a cylindrical housing provided with a piston actuatable to move through the throughbore of the housing to a cap provided with a cylindrical sleeve. Mounted within the sleeve is a hollow valve body connected to a sealing member having an end of circular cross-section and a slidable hollow cylindrical body provided with an orifice whose cross-section is substantially equal to that of the end of the sealing member. The barrel is connected to the valve body by springs. In the valve closed position the end of the sealing member is situated in the barrel orifice, preventing the dispensing of the gelatinous material; in the valve open position the barrel is pushed away from the sealing member, allowing the material to be dispensed. The barrel returns to the valve closed position after the material has been dispensed. In use, the material is introduced into the housing; weighing the valve assembly before and after dispensing enables the quantity of dispensed material to be verified.
摘要翻译：用于将测量量的凝胶状半固体材料分配到容器中的阀组件包括：圆柱形壳体，其具有可活动的活塞，该活塞可移动通过壳体的通孔到设有圆柱形套筒的盖。安装在套筒内的是中空阀体，其连接到具有圆形截面端部的密封构件和可滑动的中空圆柱体，该中空圆柱形主体设置有孔口，其截面基本上等于密封构件的端部的孔口。枪管通过弹簧与阀体连接。在阀关闭位置，密封构件的端部位于筒孔中，防止凝胶状材料的分配; 在阀打开位置，筒被从密封构件推开，允许分配材料。材料分配后，机筒回到阀关闭位置。在使用中，材料被引入到壳体中; 在分配前后对阀门组件进行称重，可以验证分配材料的数量。
