Pump housing and pump

Abstract

A pump housing for accommodating a pump unit, in particular a rotary pump, the pump housing being configured to be inserted at least partially into an external pump receptacle in an operating configuration, including a housing body having a receiving space into which the pump unit can be inserted and having an end-face access opening that forms an access to the receiving space, and including a housing member that can be coupled to the housing body in order to close the end-face access opening of the housing body in a fluid-tight manner, wherein a coupling device is provided, by means of which the housing member can be coupled to the housing body such that the housing member can be moved relative to the housing body along a longitudinal direction of the pump housing in the operating configuration.

What is claimed is: 
     
         1 . A pump housing for accommodating a pump unit, the pump housing being configured to be inserted at least partially into an external pump receptacle in an operating configuration, the pump housing comprising a housing body having a receiving space into which the pump unit can be inserted and having an end-face access opening that forms an access to the receiving space, and comprising a housing member that can be coupled to the housing body in order to close the end-face access opening of the housing body in a fluid-tight manner, wherein a coupling device is provided, by means of which the housing member can be coupled to the housing body such that the housing member can be moved relative to the housing body along a longitudinal direction of the pump housing in the operating configuration. 
     
     
         2 . The pump housing according to  claim 1 , wherein the coupling device forms a displacement area for the housing member coupled to the housing body, the housing member being displaceable within the displacement area along the longitudinal direction of the pump housing. 
     
     
         3 . The pump housing according to  claim 1 , wherein a variable axial length of the pump housing is formed by the coupling device, the variable axial length being adaptable to a depth of the external pump receptacle by means of a displacement movement of the housing member. 
     
     
         4 . The pump housing according to  claim 2 , wherein the coupling device further comprises at least one first force storage member that acts between the housing body and the housing member and by means of which a displacement movement of the housing member can be controlled in at least one displacement direction of the displacement area. 
     
     
         5 . The pump housing according to  claim 4 , wherein the at least one first force storage member is arranged between the housing member and the pump unit that can be inserted into the housing body, wherein the at least one first force storage member controls the displacement movement of the housing member in the at least one displacement direction and fixes the pump unit in the receiving space of the housing body. 
     
     
         6 . The pump housing according to  claim 4 , wherein the at least one first force storage member is configured as a coil spring, a wave spring, a disc spring, a rubber member and the like. 
     
     
         7 . The pump housing according to  claim 4 , wherein at least one second force storage member is provided on the housing member, which acts between the housing member and the external pump receptacle in the operating configuration of the pump housing. 
     
     
         8 . The pump housing according to  claim 7 , wherein a force of the at least one first force storage member and a force of the at least one second force storage member act on the housing member in opposite directions in the operating configuration of the pump housing, such that the displacement movement of the housing member can be controlled by the at least one first force storage member and the at least one second force storage member in opposite displacement directions of the displacement area. 
     
     
         9 . The pump housing according to  claim 7 , wherein the at least one second force storage member is configured as an elastic sealing member which, in the operating configuration, seals a fluid inlet and/or a fluid outlet on the housing member and controls the displacement movement of the housing member in an opposite direction to the at least one second force storage member. 
     
     
         10 . The pump housing according to  claim 1 , wherein the coupling device further comprises a limiting unit that limits a displacement movement of the housing member in a coupling configuration at least in a decoupling direction in which the housing member can be decoupled from the housing body. 
     
     
         11 . The pump housing according to  claim 10 , wherein the limiting unit further comprises a snap-in connection, a clip connection or the like, by means of which the housing member can be coupled to the housing body in a coupling direction and by means of which a limit stop for the displacement movement of the housing member is formed in the decoupling direction. 
     
     
         12 . The pump housing according to  claim 1 , wherein at least the housing body is made of a plastic material, a thermoplastic material, and/or a composite material. 
     
     
         13 . A pump comprising the pump unit and the pump housing with the receiving space in which the pump unit is accommodated, wherein the pump housing is configured in accordance with  claim 1 .
