To accomplish the object, provisions are made for the cover (5) to consist of a one-piece, plate-like elastomer material and for groove-like depressions (10) extending in the direction of partitions (6) to be present as a seal for the gas ducts (8). ## Claims ### Claim 1 A device for supplying a user with breathing gas, the device comprising: a housing; a plate-shaped elastomeric cover formed from one piece of elastomer material, said cover covering said housing, said cover having a plurality of groove-like depressions; a plurality of partitions defining gas ducts in said housing, each partition having a front surface, said groove-like depressions of said cover sealing said gas ducts, said cover having a reduced elastomer material thickness in an area of said groove-like depressions, each groove-like depression extending along one of said partitions such that a portion of said front surface of each partition is located within one of said groove-like depressions. ### Claim 2 (depends on 1) A device in accordance with claim 1, wherein said cover has a plurality of wall sections defining said groove-like depressions, each wall section being in contact with one of said partitions to define a connection area, each wall section having a sealing contour in said connection area with one of said partitions. ### Claim 3 (depends on 2) A device in accordance with claim 2, wherein said sealing contour comprises at least one lip portion extending along one of said partitions. ### Claim 4 (depends on 3) A device in accordance with claim 3, wherein said sealing contour comprises two said lip portions, each lip portion having a different wall thickness. ### Claim 5 (depends on 4) A device in accordance with claim 4, wherein one lip portion is parallel to another lip portion, each of said lip portions extending along one of said partitions. ### Claim 6 (depends on 1) A device in accordance with claim 1, wherein said cover has defined holes, each hole being in communication with one of said gas ducts. ### Claim 7 (depends on 6) A device in accordance with claim 6, further comprising a connection plate having gas ports corresponding to said holes of said cover, said connection plate bracing said cover against said housing. ### Claim 8 A device for supplying a user with breathing gas, the device comprising: a respirator housing; a plurality of partition structures defining gas ducts within said respirator housing, each partition structure having a partition wall with an outer respirator housing cover contact surface, said partition wall defining a partition structure contour; an elastic respirator housing cover formed from a unitary piece of elastomer material, said respirator housing cover having a plurality of partition covering sections defining a plurality of partition receiving grooves, each partition receiving groove having a partition receiving groove contour corresponding to said partition structure contour of one of said partition structures, each partition receiving groove having an elastomer material thickness that is less than an elastomer material thickness of one of said partition covering sections, said respirator housing cover engaging said respirator housing such that each partition receiving groove receives said partition wall of one of said partition structures, each partition covering section engaging said outer respirator housing cover contact surface of one of said partition structures to seal said partition structure, whereby said respirator housing cover seals said respirator housing. ### Claim 9 (depends on 8) A device in accordance with claim 8, wherein said partition covering section in contact with said partition wall defines a connection area, each partition covering section having a sealing contour in said connection area. ### Claim 10 (depends on 9) A device in accordance with claim 9, wherein said sealing contour comprises a first protruding portion having a first wall thickness, said first protruding portion extending along a first partition structure. ### Claim 11 (depends on 10) A device in accordance with claim 10, wherein said sealing contour comprises a second protruding portion having a second wall thickness, said second protruding portion extending along said first partition structure, said second wall thickness being different than said first wall thickness. ### Claim 12 (depends on 11) A device in accordance with claim 11, wherein said first protruding portion is parallel to said second protruding portion. ### Claim 13 (depends on 8) A device in accordance with claim 8, wherein each said partition covering section has elevated rim portions, each rim portion defining a hole in communication with one of said gas ducts. ### Claim 14 (depends on 13) A device in accordance with claim 13, wherein each said rim portion has an elastomer material thickness that is greater than said elastomer material thickness of said partition covering section. ### Claim 15 (depends on 13) A device in accordance with claim 13, further comprising a connection plate having gas ports, each gas port being in communication with one of said holes of said respirator housing cover, said connection plate engaging said respirator housing cover such that said respirator housing is pressed against said respirator housing. ### Claim 16 A device for supplying a user with breathing gas, the device comprising: a respirator device having a respirator housing with an outer housing surface; a plurality of partition walls defining gas ducts within said respirator housing, each partition wall having an outer contact surface; a respirator housing cover formed from an integral piece of elastomer material having an outer wall with an inner housing contact surface, said respirator housing cover having a plurality of elevated partition covering sections defining a plurality of partition wall receiving recesses, each partition wall receiving recess following a contour of one of said partition walls, each partition wall receiving recess having an elastomer material thickness that is less than an elastomer material thickness of one of said elevated partition covering sections, said inner housing contact surface engaging said outer housing surface such that each partition wall receiving recess receives one of said partition walls and each partition covering section engages said outer contact surface of one of said partition walls, whereby said respirator housing cover seals said respirator housing. ### Claim 17 (depends on 16) A device in accordance with claim 16, wherein said outer wall of said respirator housing cover defines a respirator housing contour, said outer housing surface defining a respirator housing contour, said respirator housing contour being substantially identical to said respirator housing contour. ### Claim 18 (depends on 16) A device in accordance with claim 16, wherein said respirator structure has a gas inspiration port and a gas expiration port in communication with one of said gas ducts. ### Claim 19 (depends on 16) A device in accordance with claim 16, wherein each elevated partition covering section has elevated rim portions, each rim portion defining a hole in communication with one of said gas ducts, each rim portion having an elastomer material thickness that is greater than said elastomer material thickness of said partition covering section. ### Claim 20 (depends on 19) A device in accordance with claim 19, further comprising a connection plate having gas ports, each gas port being in communication with one of said holes of said elevated partition covering section, said connection plate engaging said respirator housing cover such that said respirator housing is pressed against said respirator housing.
