Material container (the P for including in the fluid of number (newton) equal dose of injection device conveying definition, there is the equipment (1) one free insurance mechanism and dose delivery mechanism in a shell to be arranged to the shell along the longitudinal axis, shell (1) is couple to shell (3) and is suitable for receiving reservoir P progress flowing materials, free insurance mechanism includes which axial (established angle α) that can immovably pass through definition around two opposite directions of shell of setting sleeve (5), sleeve (5), which are arranged, has the equipment strained during setting the equipment of sleeve (5) by rotation with spring (10) The dose release mechanism include eye bolt (6) and piston rod (4) which can not be with the setting sleeve (5) of interior axial movement, during piston rod (4) and the equipment of eye bolt (6), the device, so that the eye bolt (6) is fixed with piston rod (4), and it transmits each dosage piston rod (4) and is set and pass through distance as defined in one along shell (1), due to the expansion and rotation eye bolt (6) of spring (10), piston rod displacement (4) makes flowing material from reservoir (P. Injection device according to the present invention has been conveyed for conveying subsequent dosage in the flowing material of number (newton) dosage of the determination configured with the loading device that Interrupt methods prevent, and Interrupt methods include at least one longitudinal protrusion (5.1) it is located at close to remote setting sleeve (5) on its inner surface and at least one vertical arms (4.2) it is located at the proximal end (4) of piston rod, at least one longitudinal protrusion (5.1) at least one vertical arms (4.2) the fluid conveying substance for being blocked in number (newton) dosage of the determination each other is that one kind prevents direction of rotation setting sleeve (5) by entire established angle α (equipment).
