Abstract
A pickling machine includes a carrier, a plurality of needles mounted to the carrier, a valve for controlling the supply of brine to the needles, and a pressure cylinder associated with each of the needles for buffering them. The valve includes, for each pair of needle and pressure cylinder, a separate valve for individually closing off the pressure cylinder.

A pickling machine comprising:
- a carrier,
- a plurality of needles mounted to said carrier,
- valve means for controlling the supply of brine to said needles, and
- a pressure cylinder associated with each of said needles for buffering the same,
- wherein said valve means comprise, for each pair of needle and pressure cylinder, a separate valve for individually closing-off said pressure cylinder.

A pickling machine, comprising:
- a carrier,
- a plurality of needles mounted to said carrier,
- a pressing member movable relative to said carrier in a longitudinal direction of said needles, and
- valve means controlling the supply of brine to said needles, said valve means being actuated in accordance with the relative movement of said pressing member and said carrier,
- wherein said pressing member acts upon said valve means through the intermediate of a cam having a control contour which causes said valve means to be adjusted gradually and steplessly in accordance with a distance travelled by the pressing member relative to the carrier, so that the amount of brine flowing through said valve means per time unit depends on the depth to which said needles penetrate into an item to be pickled.
