摘要:
Die Erfindung betrifft eine Vorrichtung (1) , mit welcher z. B. als Misch- und Dosiergerät Ein- oder Mehrkomponentenmassen, insbesondere eine Basiskomponente und eine Katalysatorkomponente von Abdruckmassen für den Dentalbereich aus wenigstens einer Kartusche (5a, 5b) ausgetragen werden können, wobei jeder Kartusche ein verschiebbar gelagerter Stempel (7a, 7b) zur Druckbeaufschlagung der Kartusche (5a, 5b) zugeordnet ist. Der Aufbau der Vorrichtung (1) wird dadurch vereinfacht, dass dem wenigstens einen Stempel (7a, 7b) zur Betätigung ein Kolben oder ein Zylinder (7a) einer hydraulisch betätigbaren Kolben-Zylinder-Einheit (8) mit einem wenigstens eine Pumpe (13) und einen Vorratsbehälter (9) umfassenden Hydraulikkreislauf zugeordnet ist. Weiter betrifft die Erfindung eine Ventilanordnung für eine derartige Vorrichtung.

The portable dispenser has individual supply chambers (12) that communicate with a mixing chamber (16). Each of the supply chambers (12) has a doser (26) to move fluid compositions form the supply chamber (12) to the mixing chamber (16). The mixing chamber (16) has a mixer (32) to allow it to form a homogenous mix of the individual compositions. Flexible side walls (50) of the mixing chamber (16) allow the homogenous mixture to be squeezed out of the mixing chamber (16).

The present invention relates to a dynamic mixer for mixing at least a first paste and a second paste to produce a dental substance, the mixer (10) comprising:
a mixing chamber (20); an inlet opening (21) for the first paste; an inlet opening (22) for the second paste; a first flow path extending from the inlet opening (21) for the first paste to the mixing chamber (20); a second flow path extending from the inlet opening (22) for the first paste to the mixing chamber (20); wherein:
the first flow path has a minimal cross-sectional area (Amc) of above 4,0 mm 2 ; the second flow path has a minimal cross-sectional area (Amb) greater than the minimal cross-sectional area (Amc) of the first flow path.
摘要:
The invention relates to a device for mixing two pasty materials, in particular a dental moulding compound with a catalyst material, said device being provided with a housing (42), which has a mixing chamber (45) with at least two inlets (68, 70) for the two pasty materials and an outlet (52) for the mixed pasty materials. The device is also provided with a mixing element (38), which is located in a driven manner in the mixing chamber (45) and is mounted in the housing (42) so that it can rotate about its longitudinal axis (72). The housing (42) has a coupling section (46), which is located upstream of the mixing chamber (45) and comprises two coupling openings (55, 57) that are designed to connect to two discharge openings (28, 30) of a device (10) for discharging the two pasty materials. First and second channels (64, 66), which extend through the coupling section to the inlets (68, 70) of the mixing chamber (45), are connected to the coupling openings (55, 57). The two channels (64, 66) are configured in such a way that for the first channel (64), the length of time required by the pasty material, starting from its entry into the coupling opening (55) of the coupling section (46) until it enters the inlet (68, 70) of the mixing chamber (45) of the housing (42), is greater than in the second channel (66).
