Definitions

• the subject of the present invention is a plate-valve with free microbeads, which is mainly intended to allow the filling and/or the emptying of any cylinder of any reciprocating compressor or any reciprocating pump whatsoever, whether said compressor or said pump either with a piston, with a membrane or with any volume variation device known to those skilled in the art.
• Passive pump valves There are many types of compressor valves or so-called “passive” pump valves, i.e. the opening and closing of which are controlled by the pressure difference between an upstream volume and a downstream volume. between which they stand. Passive dampers therefore differ from so-called “piloted” dampers, whose opening and closing are operated by an actuator.
• Passive compressor valves can in particular be reed, plate, or concentric segments, they can also take the form of “poppet valves” such as those produced by the company “Burckhardt” and made up of microvalves each cooperating with a spring.
• Passive compressor valves can be metallic or non-metallic.
• PEEK also known as “Polyetheretherketone” which is a material which offers in particular advantageous anti-abrasive properties.
• valves constitute a mass-spring assembly with a natural frequency. As such, they are designed to operate under relatively precise speed or even load conditions for the compressor they equip. [8] Indeed, if said compressor operates at a speed that is too far from the optimum speed of the passive valves that said compressor includes, the energy efficiency of said valves deteriorates, as does their durability.
• the passive compressor valves must open as soon as the smallest pressure difference prevails between the upstream volume and the downstream volume between which they are interposed, then, once open, oppose the less possible when passing gases.
• Passive compressor valves generally include a spring which returns them to contact with their seat
• the force exerted by said spring on the valve with which it cooperates must be low enough so that, firstly, the gases can open said valve under a low differential pressure, and secondly, fear not excessively laminating said gases passing through said valve, rolling forming an irrecoverable energy loss.
• said spring must be firm enough to bring said valve back to its seat quickly when the pressure difference reverses, in order to limit back-flow and obtain the best possible volumetric efficiency from the compressor.
• Valve wear is generally greater when operating under aggressive chemical and/or particulate conditions.
• fouling of said valves can lead to their sealing and/or permeability being degraded.
