The invention relates to a device for the controlled guidance of a polymer melt. Said device comprises a housing (1) having an inlet channel (5) and an outlet channel (6) for the polymer melt in which housing a control element can be displaced between the exits of the inlet channel (5) and the outlet channel (6) perpendicular to the inlet channel (5) and the outlet channel (6) in a sealing manner. A rotatable pin (2, 15) is used as the control element and has a flow channel (3, 16) for the polymer melt to flow through and can be rotated from a first to a second position by means of a rotary arm (9). The aim of the invention is to provide a device of the above type which is compact, inexpensive and allows various functions to be carried out with few different components. For this purpose, the flow channel (3, 16) is eccentric in relation to the rotatable pin (2, 15).
An apparatus for controlled feeding of a plastic melt, comprising a housing provided with an inlet passage and an outlet passage for the plastic melt, in which a control element may be moved between the mouths of the inlet passage and the outlet passage transverse to the inlet passage and the outlet passage in a sealing manner, and a rotatable pin serving as the control element has a flow passage for the plastic melt and can be rotated from a first to a second position by means of a rotary arm wherein the flow passage is eccentrically situated in the rotatable pin, the pin is a screen holder pin which in the flow passage accommodates a filter disk as a screen, in the first position the plastic melt being filtered and flowing through the flow passage and in the second position the flow passage being aligned with a bore in the housing through which the filter disk may be removed, the pin being rotated by more than 90° from the operating position into the exchange position.
