The liquid separator has a cyclone 1 with a separating chamber 2 including gas supply 3 and gas discharge 4 and a tank 5 which is connected to the cyclone 1 via a connection opening 6. The interior of the tank 5 is filled at least partially with a porous open-pore material 7 in order to interrupt the flow, dampen the flow, dampen the oscillations and/or discharge the liquid. ## Claims ### Claim 1 A liquid separator comprising: a tank; at least one cyclone having a separating chamber and a transition region between said separating chamber and said tank; a gas supply, a single gas discharge and said tank, each of said gas supply, said gas discharge and said tank being in communication with said separating chamber; a connection opening disposed between said separating chamber and said tank, said connection opening being the sole outlet for separated gas from said tank to leave said tank; and a porous material at least partially disposed inside at least one of said tank, said connection opening, and said transition region of said at least one cyclone. ### Claim 2 (depends on 1) The liquid separator of claim 1, wherein said tank includes a liquid storage region and a transition region between said separating chamber and said tank. ### Claim 3 (depends on 2) The liquid separator of claim 2, wherein said transition region of said tank conducts the liquid components removed from a gas flow in said separating chamber into said liquid storage region. ### Claim 4 (depends on 1) The liquid separator of claim 1, wherein said porous material has a pore volume that includes at least approximately 30% pores to material. ### Claim 5 (depends on 1) The liquid separator of claim 1, wherein said porous material has an average pore diameter approximately 10% less than a diameter of said connection opening. ### Claim 6 (depends on 1) The liquid separator of claim 1, wherein said porous material has an average pore diameter approximately 0.1% less than a diameter of said connection opening. ### Claim 7 (depends on 1) The liquid separator of claim 1, wherein said porous material is a non-woven material. ### Claim 8 (depends on 7) The liquid separator of claim 7, wherein said porous material is a non-woven plastic material. ### Claim 9 (depends on 1) The liquid separator of claim 1, wherein said porous material includes a solid material formed from at least one of a metal, plastic, rubber, ceraic, glass, nylon, glass fiber, and foam material. ### Claim 10 (depends on 1) The liquid separator of claim 1, wherein said porous material is disposed only around a region proximate said connection opening of said tank and said separating chamber. ### Claim 11 (depends on 1) The liquid separator of claim 1, wherein said porous material generally fills a circumferential extent of a tank entrance of said tank. ### Claim 12 (depends on 1) The liquid separator of claim 1, wherein said porous material is at least partially fixed by at least one of welding, gluing, and clipping. ### Claim 13 (depends on 1) The liquid separator of claim 1, wherein said tank includes a discharging member distinct from said gas discharge for discharging liquid. ### Claim 14 (depends on 13) The liquid separator of claim 13, wherein said discharging member is one of a valve, a siphon, and a discharge pipe. ### Claim 15 A method of separating a liquid-contaminated gas comprising: supplying the liquid-contaminated gas to a cyclone; separating liquid components from the liquid-contaminated gas; discharging a gas from said cyclone; moving said liquid components from said cyclone to a tank through a connection opening, said connection opening being the sole outlet for separated gas from said tank to leave said tank; holding in said tank said liquid components from the liquid-contaminated gas; and providing a porous material at least partially disposed inside said tank, said connection opening, and a transition region between said separating chamber and said tank of said cyclone. ### Claim 16 (depends on 15) The method of claim 15, wherein said porous material interrupts a gas flow to minimize the formation of turbulences. ### Claim 17 (depends on 16) The method of claim 16, wherein said porous material dampens a gas flow to minimize oscillating air columns in at least one of said cyclone, said tank, and said transition region.
