摘要： A shaft device for a bellows-type gas meter. A first eccentric cam assembly and an element having a radial groove are both coupled to the shaft. A second eccentric cam assembly having an opening is placed on the shaft. A rotatable insert element is inserted in the opening in the second eccentric cam assembly. A follower is provided on the insert element for engaging the radial groove in the element coupled to the shaft. A radial protrusion is provided for axially locking the shaft by rotating the insert element. The angle between the centerline of the first eccentric cam assembly and the centerline of the second eccentric cam assembly is adjusted by rotating the insert element.

摘要： A bellows-type gas meter comprises two compartments each having a diaphragm as well as a shaft common to said two compartments, said shaft having two eccentric cam assemblies, one of said eccentric cam assemblies being connected with the crank assemblies of said diaphragms and the other one of said eccentric cam assemblies being connected with the crank assemblies of two valves creating in a cyclic mode passages between the four chambers into which said two compartments are divided by said diaphragms and a gas inlet or a gas outlet respectively, said two eccentric cam assemblies being displaced relative to each other by an angle so that each such valve, during the chamber filling cycle, closes before the diaphragm operating in conjunction therewith moves into its final position, the eccentric cam assembly connected with said valves being provided with a disk cam assembly for each such valve, said disk cam assemblies being accommodated on said common shaft, the form of each such disk cam engaging with a substantially longitudinal opening of the crank assembly for the valve operated thereby not being circular so that the opening mode of each such valve is in a relationship with the diaphragm mode of motion, thereby keeping the error of the bellows-type meter small.
摘要翻译：波纹管式燃气表包括两个隔室，每个隔室具有隔膜以及与所述两个隔室共用的轴，所述轴具有两个偏心凸轮组件，所述偏心凸轮组件中的一个与所述隔膜的曲柄组件连接，另一个所述偏心凸轮组件中的一个与两个阀门的曲柄组件连接，在四个室之间以循环模式通道形成，所述两个隔室分别由所述隔膜分开并分别插入气体入口或气体出口，所述两个偏心凸轮组件相对于彼此移位一定角度，使得每个这样的阀在腔室填充循环期间关闭，之后隔膜与其一起运动并移动到其最终位置，与所述阀连接的偏心凸轮组件设置有盘式凸轮组件对于每个这样的阀，所述盘形凸轮组件容纳在所述公共轴上，每个这样的盘的形式 m与曲柄组件的基本上纵向的开口接合，用于所操作的阀，因此不是圆形的，使得每个这样的阀的打开模式与膜片运动方式成关系，从而保持波纹管式计量器的误差小。
