    • It is based on a cylindrical valve body (1) comprising two chambers, namely a high-pressure chamber (3) and a low-pressure chamber (4) which are separated by a partition (2) that is traversed by a shaft (7), the two ends of which are topped with pistons (5 and 6) which move inside the respective chambers (3) and (4), such that upon receiving gas at a suitable pressure, the piston (5) in the high-pressure chamber (3) moves such as to pull the other piston (6) against a spring (8), thereby pulling the piston (6) which is disposed between the inlet (10) for the gas from the respirator and the gas outlet (11) to the patient, so as to provide a very short closure time as well as a hermetic closure during the interruption. The passage of air from the high-pressure source to the high-pressure chamber (3) is controlled by a servo-assisted solenoid valve which is in turn controlled by a computer or an autonomous electronic device.
    • 它是基于一个圆柱形阀体(1),它包括两个腔室,即高压腔室(3)和低压腔室(4),它们由一个由轴(7)穿过的隔板(2)分开, ),其两端顶上在相应的腔室(3)和(4)内移动的活塞(5和6),使得在适当的压力下接收气体时,活塞(5)处于高压 室(3)移动以将另一活塞(6)拉靠在弹簧(8)上,从而拉动设置在来自呼吸器的气体的入口(10)和气体出口(11)之间的活塞(6) ),以便在中断期间提供非常短的闭合时间以及气密闭合。 空气从高压源向高压室(3)的通过由伺服辅助电磁阀控制,伺服辅助电磁阀又由计算机或自主电子设备控制。
