An injection device (210； 110) is provided that includes a housing (212； 112) adapted to receive a syringe (214； 114) that is movable between a retracted position, in which its needle (218； 118) is contained within the housing, and an extended position, in which its needle (218； 118) extends from the housing (212； 112) through an exit aperture (228； 128). The device (210； 110) includes a drive (230, 231, 232, 234； 130, 131, 132, 134) that acts upon the syringe (214； 114) to advance it from its retracted position to its extended position and to discharge its contents through its needle (218； 118). A syringe carrier (222； 122) is advanced with the syringe (214； 114) and a sleeve (219； 119) restrains the advancement of the syringe carrier (222； 122) as the syringe (214； 114) reaches its extended position. A damping element (225； 125) acts between the syringe carrier (222； 122) and the sleeve (219； 119) to cushion the impact as they come into contact, thereby reducing the transmission of energy from the impact to the components of the drive (230, 231, 232, 234； 130, 131, 132, 134) and preventing their fracture. The damping element (225； 125) also reduces the noise, which may be distressing to a user of the device (210； 110), produced when the syringe carrier (222； 122) and the sleeve (219； 119) come into contact and reduces the pain suffered by a user upon operation of the device (210； 110).제공된 주사 장치(210； 110)는 주사기 캐리어와 슬리브가 접촉함으로써 충격을 완충하도록 주사기 캐리어(222； 122)와 슬리브(219； 119) 사이에서 작용하여, 구동부의 부품(230, 231, 232, 234； 130, 131, 132, 134)들에 대한 충격으로부터 에너지의 전달을 감소시키고 파손을 방지하는 댐핑 요소(225； 125)를 포함한다. 댐핑 요소(225； 125)는 또한 주사기 캐리어(222； 122)와 슬리브(219； 119)가 접촉할 때 만들어져 장치(210； 110)의 사용자를 괴롭힐 수 있는 소음을 감소시키고, 장치(210； 110)의 동작으로 사용자가 받을 수 있는 고통을 감소시킨다.
