    • Plastics material injected through an entry point of a mould at the location (8) is caused to deflect around a pin which creates the hole (14) in a guard (5), so as to increase the balance of flow of material to either side of the pin (9). In order to minimize the tendency for the plastics material to bend out of shape the tip of the needle embedded within an enlarged portion (13) the mould is formed such that the mould material is initially encouraged to divide and flow through outer thickened regions (10) surrounding a thinner portion. At point (12) the plastics material is therefore caused to slow down resulting in greater equalization of the flow speed of the plastics material to either side of the needle tip.
    • 通过位于(8)处的模具的入口注入的塑料材料被围绕销钉(围绕销钉)偏转,该销在防护件(5)中产生孔(14),以增加材料流向两侧的平衡 (9)。 为了最小化塑料材料弯曲变形的趋势,针头的尖端嵌入在扩大部分(13)内,模具被形成为使得最初鼓励模具材料分流并流过外部加厚区域(10 )围绕较薄的部分。 在点(12),因此使塑料材料减速,从而使塑料材料流动速度更大程度地平衡到针尖的任一侧。

    • A knob is rotated from its zero position to set a dose. This rotates an indexer, which through its peg turns a ring by pushing on one of the teeth. A position is reached wherein the free end portion of the peg meets a cam surface. On continued rotation of the knob, the peg is forced radially inwards to clear the tooth that it has just been pushing against. The ring, having been shifted through one-seventh of a complete revolution is then left stationary while the knob is turned further to whatever dose is required. When a syringe actuation trigger is pressed, the knob winds back again to its zero position, taking with it the indexer. The peg is still held clear of the ring until it hits the sloping side of the tooth following the one which it had previously pushed.
    • 旋钮从其零位旋转以设定剂量。 这使一个分度器旋转,该分度器通过推动其中一个齿来转动环。 达到一个位置,其中钉的自由端部与凸轮面相遇。 在旋钮继续旋转时,钉子被径向向内推动以清除刚刚推动的牙齿。 已经转移到完整旋转的七分之一的环然后保持静止,而旋钮进一步转动到所需的任何剂量。 当按下注射器启动触发器时,旋钮再次回到其零位置,并带有分度器。 钉子仍然保持清除环,直到它撞到与之前推动的牙齿的倾斜侧面。
