The present invention proposes a device (50) for preparing a beverage from a food substance contained in a capsule (24) by injection of a liquid into the capsule (24) provided to the device (50). Said liquid is provided by a pump of the device, said device comprising an extraction head (20) having an aperture (2.2) for inserting a capsule (24) into a brewing chamber (25) of the device. The brewing chamber (25) is defined by an upper and a lower enclosing member (10a, 10b), a closing mechanism (1) to selectively enclose said capsule by a relative displacement of said enclosing members. The enclosing members are designed for being transferred between an open insertion position for inserting a capsule (24) into the brewing chamber (25) and a closed injection position for enclosing the capsule within the brewing chamber (25), and adjustment means (3a, 3b, 9b, 9c, 7a, 7b, 8a) connected to at least one of said enclosing members (10a, 10b) in order to adjust the relative position of the enclosing members and hence the closing force of the closing mechanism (1).

1. A device for preparing a beverage from a food substance contained in a capsule by feeding a liquid into the capsule provided to the device, wherein the liquid is fed by an internal or external water supply, the device comprising: a housing comprising an extraction head having an aperture for inserting a capsule into a brewing chamber of the device, the brewing chamber is defined by an upper enclosing member and a lower enclosing member;a closing mechanism to selectively enclose the capsule by a relative displacement of the enclosing members, wherein the enclosing members are designed for moving between an open insertion position for inserting a capsule into the brewing chamber and a closed position for tightly enclosing the capsule within the brewing chamber, the closing mechanism comprises a knee lever comprising an upper rod and a lower rod connected to each other by a first axle, the closing mechanism further comprises a second axle extending through the upper rod and mounting the closing mechanism inside the extraction head, and a connection member integral with the second axle connects the closing mechanism to a handle exterior to the housing of the device; andadjustment means connected to at least one of the enclosing members for adjusting the relative position of the enclosing members and hence the closing force of the closing mechanism in the closed position. 2. The device of claim 1, wherein the adjustment means comprises a means selected from the group consisting of eccentric means and cam means that allow the closing force of the closing mechanism to be varied. 3. The device of claim 1, wherein the relative position of the enclosing members is adjusted by the adjustment means without operating the closing mechanism. 4. The device of claim 1, wherein the first axle of the closing mechanism is eccentric. 5. The device of claim 2, wherein a biasing force of the closing mechanism can be adjusted. 6. The device of claim 4, wherein the eccentric first axle of the closing mechanism is rotatable. 7. The device of claim 4, wherein the adjustment means comprise at least one geared disc member connected to the first axle of the knee lever closing mechanism. 8. The device of claim 7, wherein a rotation of the disc member enables an adjustment of a distance between the center of the first axle and the second axle, and the second axle is an axle of suspension of the upper enclosing member of the knee lever closing mechanism. 9. The device of claim 8, wherein the distance can be adjusted by less than 1 mm. 10. The device of claim 7, wherein the disc member is engaged by holding means which interlock with the geared disc member in order to prevent unintended rotation of the first axle. 11. The device of claim 7, wherein the disc member is provided with a connection means to connect a tool in order to disengage the holding means and enable a rotation of the disc member. 12. The device of claim 11, wherein the connection means is an aperture provided in the center of the disc member. 13. The device of claim 1, wherein the adjustment means are connected to the second axle, and the second axle is an axis of suspension of the upper rod of the closing mechanism. 14. The device of claim 13, wherein the adjustment means comprise at least one rotatable disc member mounted at a support member by means of a cam protruding in a radial direction. 15. The device of claim 14, wherein a plurality of protruding cams are distributed over a circumference of the disc member such that they can selectively be mounted at the support member in order to adjust the position of the axis of suspension of the knee lever closing mechanism. 16. The device of claim 15, wherein the cams protrude to a different extent in the radial direction. 17. The device of claim 16, wherein the adjustment means comprise a shaft member connected between the disc member and the knee lever closing mechanism. 18. The device of claim 17, wherein the shaft member comprises at least one circular recess concentric to the shaft member and extending in a longitudinal direction of the shaft member which abuts on a circular support member of the extraction head. 19. The device of claim 18, wherein a plurality of graded circular recesses are distributed over a circumference of the shaft member and can be selectively brought to abut on the support member. 20. The device of claim 1, wherein the capsule contains a food substance selected from the group consisting of ground coffee, soluble coffee, tea, cocoa and milk. 21. The device of claim 1, wherein the capsule is a sealed capsule which is open after liquid is inserted into the capsule due to the increased pressure in the capsule. 22. A device for preparing a beverage contained in a capsule by feeding a liquid into the capsule comprising: a housing comprising an extraction head having an aperture for receiving a capsule in a brewing chamber of the device, the brewing chamber is defined by an upper enclosing member and a lower enclosing member;a closing mechanism to selectively enclose the capsule by movement of the enclosing members, the enclosing members moving between an open insertion position for inserting a capsule into the brewing chamber and a closed position for enclosing the capsule within the brewing chamber, the closing mechanism comprises a knee lever comprising an upper rod and a lower rod connected to each other by a first axle, the closing mechanism further comprises a second axle extending through the upper rod and mounting the closing mechanism inside the extraction head, and a connection member integral with the second axle connects the closing mechanism to a handle exterior to the housing of the device, andan adjuster connected to at least one of the enclosing members and so constructed and arranged to adjust the relative position of the enclosing members and thereby the closing force of the closing mechanism in the closed position.
