A driving and dosing device for an injection device for administering a liquid product, in particular a drug, wherein product dosages to be administered can be set repeatedly using the driving and dosing device, wherein the driving and dosing device comprises: a) a housing and a dosing member which can be gripped in particular by the user of the driving and dosing device and which can be rotated relative to the housing in order to set a product dosage to be administered; b) an activating member which can be activated in particular by the user of the driving and dosing device and which can be shifted relative to the dosing member in order to deliver the product dosage set; c) an advancing member, the distal end of which is designed to act on a piston of a product container which can be attached to the driving and dosing device; d) an abutment, wherein the advancing member can be moved relative to the abutment in a delivering direction, in order to be able to cause the product dosage set to be delivered; e) at least one spring (11; 11a, 11b) which acts between the advancing member and the abutment and is biased in the device as delivered, wherein the spring (11; 11a, 11b) is biased with an amount of energy such that it can deliver, in multiple individual deliveries, the maximum product amount which can be delivered from the attachable product container; f) a rotational member which, when rotated relative to the housing, enables the at least one spring (11; 11a, 11b) to move the advancing member in the delivering direction; g) and at least one coupling (9e, 1b) which, when the activating member is activated, allows the rotational member to rotate relative to the housing and, when the activating member is released, blocks the rotational member from rotating relative to the housing, wherein h) the at least one spring (11; 11a, 11b) comprises at least a first helical pressure spring and a second helical pressure spring, wherein the first pressure spring is supported on the abutment and an intermediate member, and the second pressure spring is supported on the intermediate member and the advancing member, characterised in that i) the intermediate member couples the advancing member, rotationally fixed, to the housing or to the abutment. a) a housing and a dosing member which can be gripped in particular by the user of the driving and dosing device and which can be rotated relative to the housing in order to set a product dosage to be administered; b) an activating member which can be activated in particular by the user of the driving and dosing device and which can be shifted relative to the dosing member in order to deliver the product dosage set; c) an advancing member, the distal end of which is designed to act on a piston of a product container which can be attached to the driving and dosing device; d) an abutment, wherein the advancing member can be moved relative to the abutment in a delivering direction, in order to be able to cause the product dosage set to be delivered; e) at least one spring (11; 11a, 11b) which acts between the advancing member and the abutment and is biased in the device as delivered, wherein the spring (11; 11a, 11b) is biased with an amount of energy such that it can deliver, in multiple individual deliveries, the maximum product amount which can be delivered from the attachable product container; f) a rotational member which, when rotated relative to the housing, enables the at least one spring (11; 11a, 11b) to move the advancing member in the delivering direction; g) and at least one coupling (9e, 1b) which, when the activating member is activated, allows the rotational member to rotate relative to the housing and, when the activating member is released, blocks the rotational member from rotating relative to the housing, wherein h) the at least one spring (11; 11a, 11b) comprises at least a first helical pressure spring and a second helical pressure spring, wherein the first pressure spring is supported on the abutment and an intermediate member, and the second pressure spring is supported on the intermediate member and the advancing member, characterised in that i) the intermediate member couples the advancing member, rotationally fixed, to the housing or to the abutment.
