The invention claimed is: 1. Closing device for closing channels in which pressure fluid is conveyed in a housing, into which a cartridge-type closing member is mounted in a pressure-fluid-tight manner, wherein for sealing the closing member in an accommodating bore of the housing that is provided for the closing member, at least one sealing body is arranged between the closing member and the accommodating bore, wherein the sealing body is configured as a sleeve member, whose peripheral surface is arranged between the accommodating bore and the closing member for sealing purposes, and is subjected to a defined surface pressure in sections, wherein the accommodating bore and the closing member are respectively provided with at least one stepped portion decreasing in diameter in a joining direction of the closing member, with an annular chamber being provided between the stepped portion of the closing member and the stepped portion of the accommodating bore, in which chamber the sleeve member extends in a pressure-fluid-tight manner to bridge an axial distance (X) that exists between the two stepped portions. 2. Closing device as claimed in claim 1, wherein the sleeve member is made of elastic material. 3. Closing device as claimed in claim 1, wherein the closing member is equipped with longitudinal and transverse bores for the selective passage of pressure fluid. 4. Closing device as claimed in claim 3, wherein an electromagnetically operable valve closure member is inserted into the longitudinal bore of the closing member, which establishes a switchable hydraulic connection between the longitudinal and transverse bores. 5. Closing device as claimed in claim 3, wherein for conveying pressure fluid, the sleeve member includes at least one longitudinal and transverse bore, which overlap at least in sections the longitudinal and transverse bores of the closing member. 6. Closing device as claimed in claim 1, wherein the sleeve member is made of metal or plastics. 7. Closing device for closing channels in which pressure fluid is conveyed in a housing, into which a cartridge-type closing member is mounted in a pressure-fluid-tight manner, wherein for sealing the closing member in an accommodating bore of the housing that is provided for the closing member, at least one sealing body is arranged between the closing member and the accommodating bore, wherein the sealing body is configured as a sleeve member, whose peripheral surface is arranged between the accommodating bore and the closing member for sealing purposes, and is subjected to a defined surface pressure in sections, wherein within an annular chamber, the peripheral surface of the sleeve member abuts alternatingly at the accommodating bore and the closing member under radial bias in a pressure-fluid-tight manner, and alternating abutment surfaces of the sleeve member at the closing member and at the accommodating bore are arranged at a distance, which corresponds to an axial distance (X) between at least one stepped portion provided at the closing member and the accommodating bore. 8. Closing device for closing channels in which pressure fluid is conveyed in a housing, into which a cartridge-type closing member is mounted in a pressure-fluid-tight manner, wherein for sealing the closing member in an accommodating bore of the housing that is provided for the closing member, at least one sealing body is arranged between the closing member and the accommodating bore, wherein the sealing body is configured as a sleeve member, whose peripheral surface is arranged between the accommodating bore and the closing member for sealing purposes, and is subjected to a defined surface pressure in sections, wherein an axial and radial distance between stepped portions of the accommodating bore and the closing member and an elasticity of the sleeve member are dimensioned in such a way that a pressure-fluid-tight closure of the housing is ensured by the sleeve member irrespective of tolerances of manufacture and expansion of the closing member and the accommodating bore. 9. Closing device for closing channels in which pressure fluid is conveyed in a housing, into which a cartridge-type closing member is mounted in a pressure-fluid-tight manner, wherein for sealing the closing member in an accommodating bore of the housing that is provided for the closing member, at least one sealing body is arranged between the closing member and the accommodating bore, wherein the sealing body is configured as a sleeve member, whose peripheral surface is arranged between the accommodating bore and the closing member for sealing purposes, and is subjected to a defined surface pressure in sections, wherein the sleeve member is configured as a sleeve bowl, which is manufactured in a deepdrawing process, and a bowl bottom can be seated on a step of the closing member, a step of the accommodating bore or both. 10. Closing device for closing channels in which pressure fluid is conveyed in a housing, into which a cartridge-type closing member is mounted in a pressure-fluid-tight manner, wherein for sealing the closing member in an accommodating bore of the housing that is provided for the closing member, at least one sealing body is arranged between the closing member and the accommodating bore, wherein the sealing body is configured as a sleeve member, whose peripheral surface is arranged between the accommodating bore and the closing member for sealing purposes, and is subjected to a defined surface pressure in sections, wherein the closing member is equipped with longitudinal and transverse bores for selective passage of pressure fluid, wherein for conveying pressure fluid, the sleeve member includes at least one longitudinal and transverse bore, which at least partially overlap the longitudinal and transverse bores of the closing member, wherein the transverse bore of the sleeve member penetrates a peripheral surface of the sleeve member. 11. Closing device for closing channels in which pressure fluid is conveyed in a housing, into which a cartridge-type closing member is mounted in a pressure-fluid-tight manner, wherein for sealing the closing member in an accommodating bore of the housing that is provided for the closing member, at least one sealing body is arranged between the closing member and the accommodating bore, wherein the sealing body is configured as a sleeve member, whose peripheral surface is arranged between the accommodating bore and the closing member for sealing purposes, and is subjected to a defined surface pressure in sections, wherein the closing member is equipped with longitudinal and transverse bores for the selective passage of pressure fluid, wherein an electromagnetically operable valve closure member is inserted into the longitudinal bore of the closing member, which establishes a switchable hydraulic connection between the longitudinal and transverse bores, wherein the valve closure member is configured as a slide and/or seat valve, which is acted upon by a spring that is supported on the sleeve member.
