Pump for a lubricating system of a combustion engine

Abstract

A pump is provided for a lubricating system of a combustion engine that includes, but is not limited to a housing and a lid that together define a pump hollow space in which a pump mechanism for the pumping of lubricant of the lubricating system is arranged. The pump hollow space includes, but is not limited to at least one intake opening and at least one discharge opening. The pump additionally includes, but is not limited to a regulating valve for regulating a flow of the lubricant through the pump, which is integrated in the lid.

1 . A pump for a lubricating system of a combustion engine comprising:
 a housing;   a lid that together with the housing define a pump hollow space   a pump mechanism that is arranged in the pump hollow space and configured to pump a lubricant of the lubricating system is arranged; and   a regulating valve integrated with a component of the pump and configured to regulate a flow of the lubricant through the pump.   
     
     
         2 . The pump according to  claim 1 , wherein the component is the lid. 
     
     
         3 . The pump according to  claim 1 , wherein the component is the housing. 
     
     
         4 . The pump according to  claim 1 , wherein the regulating valve is an electromagnetically actuated valve. 
     
     
         5 . The pump according to  claim 4 , wherein the regulating valve comprises a valve housing in which an electromagnetic actuation device is arranged and a valve body that is displaceable with the electromagnetic actuation device in order to regulate the flow of the lubricant. 
     
     
         6 . The pump according to  claim 5 ,
 wherein the lid comprises a valve hollow space configured to accommodating the valve body of the regulating valve and comprises an input opening through which the lubricant flows into the valve hollow space, and further comprises an output opening through which the lubricant flows out of the valve hollow space, and   wherein the valve body is configured to move in the valve hollow space in order to open the input opening.   
     
     
         7 . The pump according to  claim 5 , wherein the lid comprises a flange connected to the valve housing. 
     
     
         8 . The pump according to  claim 7 , wherein the valve housing is connected to the flange with a seal. 
     
     
         9 . The pump according to  claim 5 , wherein the valve housing comprises a cable connection. 
     
     
         10 . The pump according to  claim 1 , wherein the regulating valve is configured to actuate dependent on an engine rotational speed of the combustion engine in order to regulate an outlet pressure of the lubricant from the pump. 
     
     
         11 . The pump according to  claim 1 , wherein the pump is a vane pump with variable displacement. 
     
     
         12 . The pump according to  claim 11 , wherein the pump comprises a plurality of pump chambers of variable volumes that are defined by a plurality of sliding vanes that are carried by a rotor is rotatably mounted in the housing in order to pump the lubricant from an intake opening to a discharge opening. 
     
     
         13 . The pump according to  claim 12 , further comprising a slide configured for displacement control,
 wherein the slide is rotatably connected to a wall of the housing by a rotary axis and internally engaged with the plurality of sliding vanes,   wherein the variable volumes of the plurality of pump chambers are variable upon rotation of the slide.   
     
     
         14 . The pump according to  claim 13 , further comprising an elastic element preloading the slide in a direction,
 wherein the lubricant in a chambers exerts a force on the slide in a second direction that is opposite to the direction in which the elastic element preloads the slide.   
     
     
         15 . A lid of a pump for a lubricating system of a combustion engine, comprising:
 a valve hollow space configured to accommodate a valve body of a regulating valve;   an input opening through which lubricant flows into the valve hollow space; and   an output opening through which the lubricant flows out of the valve hollow space.   
     
     
         16 . The lid according to  claim 15 , further comprising a flange configured to connect to a valve housing of the regulating valve.
