Planetary gear mechanisms require internal toothed gears in housings. A drive rotor and driven rotors are accommodated in a mixing space in a housing, and chemical inflow paths to the mixing space are formed in an upper portion of the housing. A mixture outflow path is formed in a lower portion of the housing. The mixing space is formed to allow the drive rotor and the driven rotors to rotate and to regulate the positions of the drive rotor and the driven rotors. Meshing the drive rotor with the driven rotors allows the driven rotors to rotate opposite to the rotating direction of the drive rotor accompanying the rotation of the drive rotor while the lower ends of the driven rotors are located above a bottom portion of the mixing space and the upper ends of the driven rotors are located below the lower surface of the lid body.

A method and device for mixing plastic from liquid components in a mixer (8) and conveying it through a line (10) into a mould (12), in particular for vacuum infusion, characterised in that the components are each pumped by means of a pump (24) from their own respective component container (22) into a mixer (8) and are mixed therein, that these volume flows are controlled by a controller (26) in such a manner that they supply the components to the mixer (8) in a specific ratio, that the pressure loss in the line (10), between a pressure sensor in one of the component supply lines (32) leading to the mixer (8) and the mould (12), is determined, and that the pressure is measured by the pressure sensor and supplied to a controller (26) which, taking into consideration the determined pressure loss, controls the volume flows such that the pumps (24) supply the components to the mixer (8) at a pressure that is greater than the ambient pressure or than another specific pressure that should not be exceeded in the mould (12) by at most the pressure loss.

The invention relates to a device for producing a multi-component mixture, comprising a mixing chamber and a mixing device, wherein the mixing device has a stirrer which is arranged in the mixing chamber and which is rotatably driven about an axis of rotation L, wherein a temperature control channel system for controlling the temperature of the stirrer and through which a temperature control medium can flow is arranged inside the stirrer.

The invention relates to a device for producing and processing a multi-component mixture, the device comprising a mixing chamber which has an outlet, wherein the device has a closure element which can be moved in the direction of a longitudinal axis L of the mixing chamber in order to open or close the outlet of the mixing chamber; wherein the device has an apparatus for controlling an axial speed of the closure element, the apparatus comprising: a hydraulic system in which a hydraulic fluid is guided; a cylinder which is connected to the nozzle closure element and cooperates with at least one chamber of the hydraulic system; and a controllable throttle gap arranged in the hydraulic system.

A dynamic mixer dispense valve and metering apparatus suitable for use in mixing and applying high viscosity, disparate viscosity, high ratio, and/or relatively immiscible two part compounds that exhibit short cure times includes a housing supporting a pair of valve assemblies each coupled to respective sources of base and accelerator components. A pair of pneumatic valve actuators control the operation of the valve assemblies to control the flow of components into a mixing chamber. Within the mixing chamber a mixer impeller is rotatably supported and coupled to a source of rotational power. An additional pneumatic valve actuator combination operates a further flow control to prevent undesired material loss following a shot cycle.Note

A mixing device includes a first feed opening for a first liquid—preferably gas-laden—plastics component, a second feed opening for a second liquid plastics component, and a discharge opening for discharging a mixture of the first and the second liquid plastics component. The mixing device has a rotating agitator for mixing the first and second liquid plastics components, and a gap remains between the agitator and the discharge opening. An adjustment device is provided which either varies the gap by a relative movement between the discharge opening and the agitator, or varies the size of the discharge opening. A regulating device is connected in signal-transmitting fashion to a sensor for determining a pressure prevailing in the mixing device. The regulating device sets the gap, or the size of the discharge opening, by the adjustment device such that the pressure prevailing in the mixing device has a predetermined value.

Provided is a shaping material supply device for use in a three-dimensional shaping apparatus, which includes a first flow path through which a shaping material flows, a nozzle that communicates with the first flow path and discharges the shaping material, and a flow rate regulation mechanism that includes a butterfly valve provided in the first flow path.
