Abstract
The device comprises a mixing chamber, leading into which there are feed lines and from which there are return lines for the plastics components and which has an outlet opening for the mixture of the said components, as well as a control and displacement plunger, which can move back and forth within the mixing chamber, interconnects the feed and return lines of each component when in a recirculation position and releases the inlet into the mixing chamber when in a mixing position. In order to achieve a transfer from the feed line to the return line without any flow resistance for at least one plastics component when in the recirculation position, it is proposed that the feed line and the return line of at least one component are arranged in line with each other and the control plunger has at least one radial slit, via which the feed line and the return line can be connected in the recirculation position and that from the feed line there branches off a bypass line, which in a radial plane opens out into the mixing chamber in a discharge opening, which in the mixing position of the control plunger is opened simultaneously with the discharge openings for the remaining plastics components, the connection between feed line and return line being closed by the control plunger. <IMAGE>
Description
afgrenes en sideledning, som udmunder i et radialt plan i en indløbsåbning til blandekammeret, der åbnes i blandestil-1 ingen af styrestemplet samtidig med indløbsåbningerne for de øvrige formstofkomponenter, idet forbindelsen mellem tilløbs- og returledningen gennem styrestemplet lukkes.For example, a lateral line which branches into a radial plane in an inlet opening to the mixing chamber is opened which is opened in the mixing style of the control piston at the same time as the inlet openings for the other plastic components, closing the connection between the supply and return line through the control piston.
