Abstract

1,235,262. Internally-meshing screw pumps. SEEBERGER K. G. MASCHINEN-UND GERATEBAU. June 16, 1969 [June 15, 1968], No. 30357/69. Addition to 1,181,193. Heading F1F. The pump disclosed and claimed in the parent Specification is improved or modified in that the stator 1 is additionally secured to the tubular body 2 by portions of the stator extending into holes 19 having enlarged ends 20. The body 2 may be hollow, Fig. 2, so that a cooling medium can flow therethrough by way of connections 17, 18, the holes 19 being formed in the inner wall 16 of the body. It is indicated that as on alternative portions of the body may extend into the stator.
