Abstract
A pump, particularly, for pasteous masses, includes a rotatable outer wheel provided with a plurality of inner teeth, a pinion rotatable inside the outer wheel eccentrically thereto and having a plurality of outer teeth, the outer wheel and the pinion forming an intermediate space therebetween, a pressure seqment located in the intermediate space between the outer wheel and the pinion, an inlet and an outlet which are offset relative one another in direction of rotation, and a filling device connected with the inlet, the filling device including a filling container and a feeding element arranged in the filling container and having a feeding direction so as to feed a mass toward the inlet.
Claims34
A pump, particularly for pasteous masses, comprising
- a rotatable outer wheel provided with a plurality of inner teeth;
- a pinion rotatable inside the outer wheel eccentrically thereto and having a plurality of outer teeth engaging with said inner teeth, said outer wheel and said pinion forming an intermediate space therebetween;
- a pressure segment located in said intermediate space between said outer wheel and said pinion;
- and
- a rotatable drive shaft;
- filling means connected with said inlet, said filling means including
- a filling container having a conical container end associated with said inlet,
- movable feeding means including a worm gear attached to the drive shaft and arranged in said filling container and having a feeding direction so as to feed a mass toward said inlet;
- a guiding bush surrounding the rotatable drive shaft and fixed in position relative to the filling container and protruding into the filling container;
- and
- an immovable stopper attached to the guiding bush and extending in a radial direction from said guide bush arranged in said conical container end for preventing entraining of a mass to be filled, in the region of said conical container end.
