Embodiment approach

[0064] According to an embodiment of the present invention, the combination pump further includes an actuating mechanism, and when the fluid pressure in the first pumping passage 122 is greater than or equal to a set value, the actuating mechanism will connect the second suction passage 131 and the second pumping passage 132 is closed, and when the fluid pressure in the first pumping passage 122 is lower than the set value, the action mechanism makes the second suction passage 131 and the second pumping passage 132 open.

[0065] According to one embodiment of the present invention, the action mechanism includes a plurality of action valves, which are driven by the medium in the first pumping passage 122 and used to control the opening of the second suction passage 131 and the second pumping passage 132 and off. In this embodiment, the action valve includes a third channel 115 provided on the main body 11 or the lower cover 13 , a first cut-off piece c that fits and is slidabl...

Abstract

The invention relates to a combination pump and a combination pump system. The combination pump comprises a main body, an upper cover and a lower cover which are located at the two opposite sides of the main body, a first pump core component arranged between the main body and the upper cover, a second pump core component arranged between the main body and the lower cover, and a rotating shaft used for connecting and driving the first pump core component and the second pump core component, wherein a first cavity used for containing the first pump core component and a second cavity used for containing the second pump core component are formed in the two opposite sides of the main body correspondingly; the combination pump is provided with a first suction channel and a first pump-out channel which are communicated with the first cavity, and a second suction channel and a second pump-out channel which are communicated with the second cavity; and the combination pump further comprises an action mechanism, and when the pressure of the fluid in the first pump-out channel is larger than or equal to a set value, the second suction channel and the second pump-out channel are closed by the action mechanism. The pump is simple in structure and small in size.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a combined pump and a combined pump system. Background technique [0002] With the high energy-consuming economic growth mode and extensive development mode, environmental problems are becoming more and more prominent, and 60%-70% of the existing vehicles are vehicles with high energy consumption and high pollution emissions, and the total amount of fuel and engine oil consumed each year It accounts for more than half of my country's annual output of refined oil. Therefore, in order to speed up the construction of a resource-saving society, energy conservation and emission reduction have become one of the important issues in the automotive industry. Since the engine is the heart of the car, how to improve the efficiency of the engine and reduce the loss of power and energy is one of the effective means to achieve energy saving and emission reduction. [0003] For example, as one of the com...
