Embodiment Construction

[0017] Such as figure 1 As shown, the characteristic map controlled lubricant pump system 1 comprises a lubricant pump 2 which can be designed, for example, as a rotary vane pump and which supplies an internal combustion engine 3 with lubricant. According to the present invention, in the lubricant pump system 1, the filter 4 is connected to the output side of the lubricant pump 2, and a pressure sensor 5 and a proportional device 6 are additionally installed, wherein the proportional device 6 can be designed as a two-position exemplary Three-way reversing valve. Evidently, according to the invention, part of the lubricant pump system 1 is an additional lubricant storage tank 7, in which lubricant (for example oil 8) collects. Regardless of whether oil 8 is mentioned afterwards, this obviously means that the same applies to any other usual lubricant.

[0018] Here, the proportional valve 6 connected in communication with the internal combustion engine 3 or the lubricant pump ...

Abstract

A lubricant pump system may include a lubricant pump controlled by a proportional valve. An actuating unit may be disposed in the lubricant pump and configured to control a delivery output of the lubricant pump. A first pressure chamber and at least one second pressure chamber may be configured to adjust the actuating unit against a spring, wherein the second pressure chamber is smaller than the first pressure chamber. In response to a failure of the proportional valve, the lubricant pump may be exclusively pressurized via the at least one second pressure chamber.

Description

technical field [0001] The present invention relates to a characteristic-map-controlled lubricant pump system having a lubricant pump for supplying lubricant to an internal combustion engine. The invention also relates to a lubricant pump for such a feature map controlled lubricant pump system. Background technique [0002] It is prior art in the art to use flow controlled lubricant pumps in internal combustion engines to approximate eg output rate and pressure to the various requirements of the internal combustion engine. Mostly this is achieved by loading an actuating unit (for example a control piston or an adjusting ring) in a lubricant pump with oil pressure originating from the main oil gallery of the internal combustion engine. The disadvantage of this control is that the control is directly related to the main oil pressure in the internal combustion engine, the flow rate, the engine rotational speed, the temperature of the lubricant and the spring force exerted on t...
