1. A valve comprising: a body with a passage opening for a medium;an actuator having a recess;a tappet, having first and second ends, disposed with clearance within the actuator recess and configured for linear movement within the recess;a longitudinally movable operating body serving as a hand key;a readjusting spring; anda tappet spring, supported in the longitudinally movable operating body, in direct, linear mechanical cooperation with the first end of the tappet, the tappet spring configured to bias the second end of the tappet towards the passage opening,wherein the tappet is in a closed position, on the passage opening, when the actuator is in a first position and the tappet is in an open position, spaced from the passage opening, when the actuator is in a second position, andwherein the operating body acts against the power of the readjusting spring, via the tappet spring, on the tappet and the actuator, respectively. 2. Valve according to claim 1, characterized in that the tappet acts directly on the passage opening. 3. Valve according to claim 1, characterized in that the tappet is comprised of an elastic material. 4. Valve according to claim 3, wherein the elastic material is synthetic rubber. 5. Valve according to claim 1, characterized in that a sealing surface of the passage opening is provided, and the actuator has a direction of motion wherein the direction of motion of the actuator is essentially perpendicular to the sealing surface of the passage opening. 6. Valve according to claim 1, characterized in that the actuator comprises a rocker-like, hinged armature. 7. Valve according to claim 1, characterized in that the motion of the actuator from the open position to the closed position is through operation of a drive, wherein the drive is provided as one of a solenoid, a mechanically movable permanent magnet, an electromotor, or a piezoelectric array. 8. Valve according to claim 1, having at least a first and a second passage opening and a first and a second tappet, each arranged at a first end and a second end of the actuator, respectively, wherein the first tappet is interacting with the first passage opening and the second tappet is interacting with the second passage opening and wherein at least the spring power of a first tappet spring pushes the first tappet in the closed position on the first passage opening, while the second tappet opens the second passage opening. 9. Valve according to claim 8, characterized in that a drive is provided, and the drive is arranged between the first and second tappets. 10. Valve according to claim 1, wherein the tappet is designed as a nipple, interacting directly with the passage opening. 11. Valve according to claim 10, wherein the nipple is designed as a double nipple having two nipple parts with a flange arranged between the two nipple parts and wherein the flange serves for fixing or arranging the nipple in the actuator. 12. Valve according to claim 1 wherein the valve is a pneumatic valve. 13. A valve, comprising: a housing with a valve space defined therein;a solenoid disposed in the housing;a web structure disposed in the valve space;a hinged armature positioned to swivel on the web structure, the armature having first and second ends and a respective recess in each end;first and second tappets disposed with clearance, respectively, in the first end recess and the second end recess of the armature, each of the first and second tappets having first and second ends and configured for linear movement within the respective recess;first and second passage openings disposed, respectively, adjacent to the first and second tappets;a first tappet spring provided in the housing in direct, linear mechanical cooperation with the first end of the first tappet and configured to urge the first tappet toward the first passage opening; anda second tappet spring provided in the housing in direct, linear mechanical cooperation with the first end of the second tappet and configured to urge the second tappet toward the second passage opening,a longitudinally movable operating body serving as a hand key provided in the housing; anda readjusting spring provided in the housing and arranged in cooperation with the moveable operating body,wherein the second tappet spring is supported in the longitudinally movable operating body,wherein the moveable operating body acts against the power of the readjusting spring, via the second tappet spring, on the tappet and the armature, respectively,wherein, in a first state of operation when the solenoid is inactive, the first tappet spring directly urges the first tappet to close the first passage opening and the second passage opening is open and fluidly coupled with the valve space, andwherein, in a second state of operation when the solenoid is active, the armature is attracted to the solenoid and the first tappet is removed from the first passage opening to fluidly couple the first passage opening with the valve space and the second tappet spring directly urges the second tappet to close the second passage opening. 14. The valve according to claim 13, wherein at least one of the first and second tappets comprises an elastic material. 15. The valve according to claim 13, wherein: each of the first and second passage openings comprises a respective sealing surface, andwherein a motion of the solenoid is in a direction that is essentially perpendicular to the sealing surfaces of the first and second passage openings. 16. The valve according to claim 13, wherein at least one of the first and second tappets is designed as a nipple interacting directly with the corresponding first and second passage opening. 17.
