This invention provides an injector for injecting food filling fluid such as pickle into raw flesh lump transported through the transportation rollerswhich can solve the conventional bubble issues that arose in piston pump when fluid was injected into injection needle group, sanitary issues and so onand can inject the food filling fluid under high pressure.A new type of pickle injector device wherein multi-needle injection groups 3a, 3b stretching vertically is descendedto stab into the transported flesh lump, allowing the pickle infusing in the flesh lump.Means for supplying pickle to injection needles 3a, 3b are configured that respectively check valves (spout valves) 13a, 13b composed of supply valves which supply the fluid to injection needles 3a, 3b through the glide of the reciprocation piston 12 inserted in the cylinder 10 of the liquid pump are provided at the front and rear upper end of the cylinder in the liquid pump, and the suction valves 14a, 14b composed of the check valves which fill pickle in the cylinder 10 are provided at the front and rear lower end of the cylinder in the liquid pump.本發明提供一種注射器，係將醃汁等的食品注入液注入由輸送輥子送來之原料肉塊中而加工，可解決以往將食品注入液送到注入針群之活塞泵發生的氣泡問題點，以及衛生上的問題點等，且能以高壓將食品注入液注入。一種醃汁注入用注射器裝置，係使垂直方向延伸之多個醃汁注入針群3a、3b下降，扎進被送來之肉塊，使醃汁浸透到該原料肉塊中。該裝置係將醃汁供應於醃汁注入針3a、3b用的手段構成液泵的液缸10，分別把藉由被嵌入液泵的液缸10的往復活塞12之滑動而將醃汁向醃汁注入針群噴出供應之由止回閥所形成的供應閥(噴出閥)13a、13b設置於液泵之液缸的前後上端部，以及醃汁填充於液缸10內之由止回閥所形成的吸入閥14a、14b設置於液缸的前後下端部。
