Abstract
The invention belongs to the technical field of automobile engine lubrication, particularly relates to a pressure stabilizing filter. The filter is internally provided with a filtering chamber which is filled with filter elements; and the side of the filtering chamber is provided with a pressure stabilizing chamber for adjusting pressure. In the technical scheme, the filter is internally with the pressure stabilizing chamber which plays a role of stabilizing pressure and storing pressure in a whole lubricating system, and the pressure stabilizing chamber can adjust the pressure of the whole lubricating system, reduce the pressure peak value in the lubricating system and continuously supply oil for a turbocharger when an engine shut down suddenly, thereby achieving the goal of protecting the turbocharger.
Description
Technical field
The invention belongs to the automotive engine lubrication technical field, be specifically related to a kind of pressure stabilizing filter.
Background technology
Along with the increasingly stringent of Abgasgesetz, turbocharger has become the basic configuration of many engines, particularly Diesel engine, and the application of turbocharger is more extensive.And have the engine of turbocharger; Its lubricating system has more strict requirement; Oil pressure scope when moving, and the oily temperature rise limit value etc. of turbocharger lubrication system during engine shutdown such as engine, but conventional at present lubricating system is difficult to satisfy above-mentioned requirements.
Summary of the invention
The purpose of this invention is to provide a kind of pressure stabilizing filter, its simple structure, and can under various operating modes, protect turbocharger, help engine reliablely and stablely to work.
For realizing above-mentioned purpose, the present invention has adopted following technical scheme: a kind of pressure stabilizing filter is provided with the filter chamber in the cleaner; Be filled with filter core in the filter chamber; The side of described filter chamber is provided with the pressure stabilizing chamber of adjustment pressure, and described cleaner is a column, and the middle part of cylinder is made as pressure stabilizing chamber; Filter chamber's ring is located at the outside of pressure stabilizing chamber; One side of filter chamber is communicated with the input of cleaner, and opposite side is communicated with the output of cleaner, and described pressure stabilizing chamber is provided with piston towards the input of cleaner and/or a side of output; Piston can move along the direction that pressure stabilizing chamber limits, and described piston is arranged in the inner end face of pressure stabilizing chamber and presses voltage regulation part to link to each other with the storage that is arranged on pressure stabilizing chamber.
Can know by technique scheme; The present invention is provided with pressure stabilizing chamber in cleaner, pressure stabilizing chamber plays the effect of voltage stabilizing and storage pressure in whole lubricating system, and it can regulate the pressure of whole lubricating system; Can reduce the pressure peak in the lubricating system; And when engine is shut down suddenly, realize continuing fuel feeding to turbocharger, reach the purpose of protection turbocharger.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of pressure stabilizing filter is provided with filter chamber 74 in the cleaner 70, be filled with filter core 71 in the filter chamber, and the side of described filter chamber 74 is provided with the pressure stabilizing chamber 75 of adjustment pressure.
Machine oil in the lubricating system filters through obtaining behind the filter core 71, under the effect of pressure stabilizing chamber 75, reduces pressure oscillation simultaneously, realizes the purpose that the voltage stabilizing storage is pressed.
As shown in Figure 1, described cleaner 70 is a column, and the middle part of cylinder is made as pressure stabilizing chamber 75, and filter chamber's 74 rings are located at the outside of pressure stabilizing chamber 75, and a side of filter chamber 74 is communicated with the input of cleaner 70, and opposite side is communicated with the output of cleaner 70.
Above-mentioned set-up mode can proper extension filter chamber 74 filtration path, thereby improved filter effect, help the cleaning of machine oil, also guaranteed the functional reliability of lubricating system.
Pressure stabilizing chamber 75 has multiple implementation; Such as adopts pressure sensor and the combined mode of hydraulic pump; As preferred version of the present invention, as shown in Figure 2, described pressure stabilizing chamber 75 is provided with piston 73 towards the input of cleaner 70 and/or a side of output; Piston 73 can move along the direction that pressure stabilizing chamber 75 limits, and described piston 73 is arranged in pressure stabilizing chamber 75 inner end faces and presses voltage regulation part 72 to link to each other with the storage that is arranged on pressure stabilizing chamber 75.
Described storage presses voltage regulation part 72 can preestablish force value; When pressure stabilizing chamber 75 suffered engine oil pressures are lower than the predetermined pressure of storage pressure voltage regulation part 72; The state of pressure stabilizing chamber 75 remains unchanged, and guarantees that pressure stabilizing chamber 75 reaches the Time Created of needed oil pressure when not influencing engine start; When pressure stabilizing chamber 75 suffered pressure were higher than the predetermined pressure of storage pressure voltage regulation part 72, piston 73 was inner mobile to pressure stabilizing chamber 75 along the direction that pressure stabilizing chamber 75 limits, and makes the internal capacity of pressure stabilizing chamber 75 diminish, and it is to the energy storage effect; When pressure stabilizing chamber 75 suffered pressure diminished, piston 73 progressively returned to initial position in the external moving of the direction of storing up effect lower edge pressure stabilizing chamber 75 qualifications of pressing voltage regulation part 72 to pressure stabilizing chamber 75, made the internal capacity of pressure stabilizing chamber 75 become big, and it arrives pressure stabilization function.
Described storage presses voltage regulation part 72 can be chosen as the compression spring, and the compression spring also plays the effect of system damping, to reduce the pressure oscillation of lubricating system, can regulate the pressure oscillation in the pressure stabilizing chamber 75 simultaneously, the oil pressure in the systems stabilisation.
