Abstract: Food dispenser for free-flowing food has a piston movable in a reciprocal manner in a cylinder by a drive and having a valve (2) having a valve body (5) which is rotatable about a rotational axis (7) between a first and a second switching position. In the first switching position, a first channel (14) of valve body (5) connects a suction opening (11) and a working opening of piston (12), such that a working stroke of the piston suctions food through suction opening (11) and working opening (12) into an intermediate space. In the second switching position, a second channel (15) of valve body (5) connects working opening (12) and a dispensing opening (13) such that a second working stroke of the piston conveys food from the cylinder through working opening (12) and dispensing opening (13). The suction opening (11), working opening (12) and dispensing opening (13) are offset, spaced from one another along rotational axis (7) of the valve body (5).

Abstract: Food dispenser for portioning and dispensing free-flowing food, comprising a piston which is able to move in a reciprocal manner in a cylinder by means of a drive and having a valve (2) comprising a valve body (5) which is able to be rotatably driven exclusively about a rotational axis (7) between a first and a second switching position, in the first switching position by means of a first channel (14) delimited by the valve body (5) a fluidic connection being created between a suction opening (11) and a working opening assigned to the piston (12), such that by means of a working stroke of the piston, food is able to be suctioned through the suction opening (11) and the working opening (12) into an intermediate space, which in particular is formed in the cylinder, and in the second switching position by means of a second channel (15) delimited by the valve body (5), a fluidic connection being created between the working opening (12) and a dispensing opening (13) such that by means of a second working stroke of

Abstract: The present invention provides a nozzle apparatus for dispersing droplets of flowable material. The apparatus has a body with a vortex chamber, an inlet for feeding the flowable material thereto, and a passageway for supplying pressurized gas to the vortex chamber such that the flow of the pressurized gas is tangential to the flow of the flowable material. An outlet for dispersing droplets of flowable material out of the apparatus is in communication with the vortex chamber. The inlet and the outlet have cross-sectional areas which are equal to within ±15%. The passageway directs the pressurized gas to move in a vortex within the vortex chamber and envelope the flowable material. The cross-sectional area of the flowable material is thereby reduced and caused to accelerate through the outlet. Upon exiting the outlet, the flowable material spirals outwards and breaks into droplets of material thereby.

Abstract: A power semiconductor module in which at least one semiconductor chip with which contact is made by pressure is electrically connected via a contact element to a main connection. The contact element has two planar contact surfaces, between which a spring element is located. Irrespective of the individual position and height of a chip, the respective spring element ensures a standard contact force. Overloading of the semiconductor chips when the module is being clamped in is prevented by ceramic supporting elements.
