Abstract: An apparatus and a method for cryopreserving a plurality of cellular samples are disclosed. The apparatus may include a cooling chamber and a cooling device that may include a mechanism to cool an interior of the cooling chamber. The cooling device may further include cooling tubes that are separate from the mechanism to cool the interior of the cooling chamber and that are arranged within the cooling chamber. The cooling device may provide a flow of refrigerant through the cooling tubes and a support for supporting a plurality of vials for storing cellular samples. The support may be movable relative to the cooling tubes such that the plurality of vials may be engageable with the cooling tubes.

Abstract: Disclosed is an injector for fuel injection, with a magnet valve for controlling an injection valve, in which the magnet valve has a movable armature that can be moved onto a valve seat in the lower armature chamber. The lower armature chamber communicates fluidically with the control pressure chamber of the injection valve via bores. Via a return bore, incidental leak fuel quantities can be returned to a tank via the lower armature chamber. To prevent armature recoil upon closure of the valve seat by the armature, it is proposed that means be provided in the injector for reducing pressure fluctuations occurring in the lower armature chamber. Eliminating pressure fluctuations in the lower armature chamber leads to maximal elimination of armature recoil.

Abstract: Disclosed is a radial piston pump having a longitudinally movable pump piston in a cylinder chamber which communicates with a suction valve. A closing body of the suction valve is loaded by a valve closing spring in the direction of its valve seat affixed to the housing. The valve closing spring is supported on the pump piston. The radial piston pump is especially useful in fuel injection systems of internal combustion engines, particularly in common rail injection systems.
