Abstract: An apparatus and method for depositing flowable material comprising a chamber housing that receives and deposits flowable material, a rotary valve shaft and a piston shaft inside the chamber housing, the piston shaft rotatable in synchronization with the rotary valve shaft, wherein the piston shaft and the rotary valve shaft form a volumetric pocket to receive the flowable material, wherein the piston shaft rotates between a position that expands the volumetric pocket to draw the flowable material into the volumetric pocket, and a position that compresses the volumetric pocket to urge flowable material from the volumetric pocket.

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
