Definitions

  • This invention relates to improvements in or relating to pump impellers or turbines notably those utilized for circulating cooling water in the engines of automobile vehicles, in Washing machines and for any other pumps for home use.
  • FIGURES 1 to 4 show the rigid element or elements secured on the shaft and provided with the turbine blading, the elastic element connecting to said first rigid element or elements another rigid element constituting a movable sealing member;
  • FIGURE 5 shows the elastic element connecting to the rigid element secured on the shaft another rigid element formed with the blading and also with a radial movable sealing flange;
  • FIGURE 6 shows the elastic element connecting to the rigid element secured on the shaft a pair of other rigid elements, in this case a bladed wheel and a movable sealing ring;
  • FIGURES 7 to 11 illustrate the elastic element formed with integral blades and'carried by the rigid element connected to the shaft and carrying one or two movable sealing members.
  • All the forms of embodiment illustrated in the drawing comprise at least one rigid element 2 firmly fastened or connected to the shaft 1 and'having attached thereto an elastic element 4.
  • This elastic element 4 carries in turn at least one rigid element 3 constituting at least partially a movable sealing ring.
  • the rigid element 2 is formed with an integral the form of a single pressed disc formed with the impeller blading and the other in the form of a shaftengaging member consisting in FIGURE 3 of a simple pressed-metal flanged sleeve and in FIGURE 4 of a shouldered hub.
  • the rigid element 3 constituting the movable sealing ring consists of a simple pressed metal ring.
  • this rigid element 3 consists of a ring made from a movable sealing material such as cast-iron, ceramic, graphite, bronze, steel.
  • the rigid element 2 secured on shaft 1 consists of a shouldered or pressed sleeve connected through the elastic element 4 to the other rigid member 3 constituting the movable sealing element and the bladed portion of the impeller.
  • the rigid element 2 secured on shaft 1 consists of a shouldered or moulded hub.
  • the elastic element 4 secured on this hub carries two rigid elements, i.e. a bladed disc 5 and a movable sealing 3.
  • FIGURES 7 to 11 the elastic ring 4 secured on the rigid element 2 firmly connected to shaft 1 is formed with the blading.
  • the element 2 is an unitary part and in FIGURES 9 and 10 it is obtained by rigidly assembling two separate parts. In FIGURE 10 these two parts are separated by a certain gap for the purpose of sparing the elastic material in the part of the assembly where its presence is unnecessary.
  • the elastic element 4 carries on one side, around the shaft 1, a movable sealing ring 3.
  • two' movable sealing rings 3 are mounted on both sides ofthe elastic element 4.
  • the element 2 adapted to be distorted by expansion when force-fitted on the shaft is not in direct contact with the element 3 adapted to act as a friction element, but is connected thereto only through the medium of the elastic element, thus avoiding any distortion of said element 3 of which the operative face must remain flat if it is used for sealing a rotary joint with a side-contact joint.
  • the faces of the rigid elements which register with the elastic material may be perforated to ensure a better adherence of the elastic material.
  • An impeller for small-sized pumps which comprises an inner sleeve adapted to be rigidly force-fitted on a rotary shaft and carries outer peripheral blades, said impeller consisting of a rigid portion of which said shaftengaging force-fitting sleeve is an integral part, at least one rigid member having an annular plane face extending at right angles to the shaft axis, and a member of resilient material adapted to secure said rigid member to said rigid portion provided with said force-fitting sleeve,-
  • Patented May 17, 1966 An impeller for small-sized pumps as set forth in claim 2, wherein said rigid portion is made from a single pressed-sheet metal blank.
