摘要：
A device for regulating the delivery pressure of gases includes a valve unit having at least one valve seat and a respective closure element displaceable along an axis with respect to the valve seat which is controlled by a diaphragm. The device further includes a first spring which acts on the diaphragm in order to subject it to a preselected resilient load. A second spring is selectively activated to exert an additional resilient load on the diaphragm. The device includes a handle associated with the first and second springs in order to impose selectively the desired delivery pressure value, between a minimum value and a maximum value of pre-calibration, the pressure value being proportionally correlated with a predetermined resilient load exerted on the diaphragm.
摘要（中）：
用于调节气体的输送压力的装置包括具有至少一个阀座的阀单元和相对于由隔膜控制的阀座可相对于轴线移位的相应封闭元件。 该装置还包括作用在隔膜上的第一弹簧，以使其处于预选的弹性载荷。 选择性地激活第二弹簧以在隔膜上施加额外的弹性负载。 该装置包括与第一和第二弹簧相关联的手柄，以便在预校准的最小值和最大值之间选择性地施加期望的输送压力值，压力值与施加在第一和第二弹簧上的预定弹性载荷成比例地相关 隔膜
