Abstract: A needle register for injection apparatus for injecting liquid into food products, comprising: a needle carrier (10) forming a distribution chamber (16) for the liquid; a plurality of parallel hollow needles (12) which are held on the needle carrier (10) such that their open top ends are disposed inside the distribution chamber (16); and at least one perforated plate (30) that is removably received in the distribution chamber (16), a plurality of the needles (12) being held in the perforations of the perforated plate, characterized in that the needles (12) are firmly fitted into the perforations of the perforated plate (30).

Abstract: Device for injecting fluids into foods, with at least one fluid chamber into which is fed the fluid under pressure, with several hollow needles which each are connected with the fluid chamber or one of the fluid chambers via a valve device and movable in such a way that they puncture the foods, and with a control instrument for operating the valve devices dependent on the needle movement, wherein the valve devices are arranged on a detachable or swivellable cover of the appropriate fluid chamber.

Abstract: Device for the adjustment of the stroke length of a needle carrier (12) of a pickling machine, which can be moved back and forth in such a way that the lower deadpoint of the needle carrier is independent of the stroke length, is characterized by the fact that needle carrier (12) is articulated with an intermediate lever (24) that can be turned around a rigid axis (26) and this lever (24) is joined in turn via a connecting rod (22) with a crankshaft (18) driven in rotation, and that coupling point (32) of connecting rod (22) on intermediate lever (24) can be adjusted in a connecting link (34), which runs concentric to the axis of rotation of crankshaft (18) in the lower dead-point position of intermediate lever (24).
