Patent ID: 8770219

Claim:
A device for regulating the gas supply in a gas storage system of a biogas system, wherein the gas storage system has at least two gas stores connected in series in a cascade-like manner that each have an intermediate chamber between a gas store membrane and a protective covering the device comprises gas supply mechanisms ( 54 , 56 , 58 ), intermediate chamber pressure measuring mechanisms ( 68 , 70 , 72 ) and at least one regulating mechanism ( 80 ), wherein to each gas store ( 12 , 14 , 16 ) at least one gas supply mechanism ( 54 , 56 , 58 ) is assigned with which gas can be supplied to the intermediate chamber ( 48 , 50 , 52 ) of the respective gas store ( 12 , 14 , 16 ), wherein to each gas store ( 12 , 14 , 16 ) at least one intermediate chamber pressure measuring mechanism ( 68 , 70 , 72 ) is assigned with which the gas pressure in the intermediate chamber ( 48 , 50 , 52 ) of the respective gas store ( 12 , 14 , 16 ) can be measured, wherein the measured values of the intermediate chamber pressure measuring mechanisms ( 68 , 70 , 72 ) are supplied to at least one regulating mechanism ( 80 ), and wherein the at least one regulating mechanism ( 80 ) is designed to regulate the gas pressure in the intermediate chambers ( 48 , 50 , 52 ) of the gas stores ( 12 , 14 , 16 ), on the basis of the measured values of the intermediate chamber pressure measuring mechanisms ( 68 , 70 , 72 ), by a control of the gas supply mechanisms ( 54 , 56 , 58 ) assigned respectively to the gas stores ( 12 , 14 , 16 ).
