Machine for displacing fluid

Abstract

A machine, such as a pump or motor, includes a housing with two chambers which are delimited therein. The chambers are delimited between a partition wall which is arranged centrally in the housing and extends on all sides, and displacement members which are situated on either side of the partition wall. These displacement members perform a tilting movement as a result of which in each case a fluid volume is displaced. The housing is provided with inlets and outlets near the partition wall. The tilting movement can be produced by a combination of a rotating shaft and an eccentric.

       13 . Machine comprising a housing having housing parts which rest against one another via a separating plane, and a displacement body, in which the housing and displacement body can be pivoted with respect to one another about a tilting axis having two directions of rotation, in order to delimit a first chamber with variable volume, wherein said displacement body comprises a first displacement member which can be displaced in a substantially fluid-tight manner along the inner wall of said housing, wherein said displacement body comprises a second displacement member which is fixedly connected to the first displacement member and arranged at a distance from said first displacement member, wherein said housing comprises a partition wall, which is arranged between the displacement members, wherein said first chamber is delimited between said first displacement member and a first side of said partition wall and a second chamber is delimited between said second displacement member and a second side of said partition wall, said second side being opposite said first side, wherein said displacement members and sides of said partition wall are embodied such that said displacement members can perform a rolling movement with line sealing with respect to said sides of said partition wall, wherein said first and second displacement members delimit a wall extending over approximately 360° with said partition wall and a radially extending sealing plate being arranged between said first and second displacement member, wherein each of said chambers in each case comprises an inlet and an outlet, said inlets and outlets respectively extending directly from said chambers into said housing and are connected directly to one another, wherein said separating plane is at right angles to said partition wall and said sealing plate is retained between said housing parts. 
   
   
       14 . Machine according to  claim 13 , wherein said partition wall is integral with a housing part. 
   
   
       15 . Machine according to  claim 14 , wherein said partition wall comprises partition wall parts, the separation of which coincides with the separating plane. 
   
   
       16 . Machine according to  claim 13 , wherein said separating plane comprises the centre axis of the rotating drive of the machine. 
   
   
       17 . Machine according to  claim 13 , wherein said second displacement member, along its periphery, is situated at a substantially fixed distance from the periphery of said first displacement member. 
   
   
       18 . Machine according to  claim 13 , wherein said displacement member, on that side which is turned towards said partition wall, substantially tapers towards the free end thereof. 
   
   
       19 . Machine according to  claim 13 , wherein a rotating shaft is provided which extends through said housing and is provided with a mechanism for converting a rotating movement into a tilting movement. 
   
   
       20 . Machine according to  claim 13 , wherein said displacement member and/or said partition wall are provided with a coating which bounds said chamber. 
   
   
       21 . Machine according to  claim 13 , wherein said inlet and/or outlet of said chambers is arranged near said partition wall. 
   
   
       22 . Machine according to  claim 13 , wherein said housing comprises two housing parts and the separating plane between said parts is substantially determined by a plane which is at right angles to said tilting axis. 
   
   
       23 . Machine according to  claim 13 , comprising a motor. 
   
   
       24 . Machine according to  claim 13 , comprising a pump.
