    摘要： A differential pressure valve is disclosed, comprising: a valve body, the valve body having at least one flow inlet and one flow outlet; at least one shutter, the shutter being movable between an open position and a closed position under a differential pressure across the valve; a flow passage from the flow inlet to the flow outlet; at least one biasing member configured to bias the shutter towards a closed position so as to block the flow passage through the flow inlet. The biasing member comprises at least two springs arranged in parallel, one of the springs having at least one resonance frequency different from at least one resonance frequency of the other of the two springs.

    摘要： Disclosed herein is a differential pressure poppet valve comprising: a valve body, the valve body having at least one flow inlet and at least one flow outlet; at least one shutter guide disposed inside the valve body; at least one poppet shutter guided by the shutter guide; at least one flow passage from the flow inlet to the flow outlet, the flow passage being formed between an inside surface of the valve body and an outside surface of the shutter guide and of the poppet shutter. The valve further comprises at least one biasing member configured to bias the poppet shutter towards a closed position so as to block the flow passage through the flow inlet. To reduce impact wear at least a first damper is provided, configured and arranged to at least partly absorb impact energy of the poppet shutter when the poppet shutter opens or closes the flow inlet.

    摘要： An actuated rotary valves for reciprocating compressors used in oil and gas industry, the valve including a stator with a stator opening, a rotor with a rotor opening, and an actuation mechanism. The actuation mechanism is configured to receive a rotation motion and to actuate the rotor to perform first an axial translation moving away from the stator and then a rotation. The actuation mechanism includes an outer shaft configured to receive the rotation motion, and an inner shaft inside the outer shaft and configured to rotate the rotor. The outer shaft is configured to rotate a predetermined angular displacement while pushing the rotor away from the stator before engaging the inner shaft to rotate together with the rotor.
