The utility model solves the defects that when the existing engine VVT system is additionally provided with an external filter, the structure of the whole system is complicated, the installation is inconvenient, an oil passage needs to be additionally arranged on a cylinder cover and the difficulty degree for processing and designing the cylinder cover is increased. The utility model has the technical scheme that the camshaft hydraulic control valve for an engine VVT system comprises a valve body and a valve pipe; the valve pipe is positioned in a cylinder cover of an engine and is used for being communicated with an oil passage arranged in the cylinder cover. The utility model is characterized in that a plurality of oil holes are arranged on the valve pipe; the oil holes comprise oil inlet holes and oil outlet holes; the oil holes are mutually staggered in the axial direction of the valve pipe; a position where the oil inlet holes are positioned on the valve pipe is provided with a circular sleeve-shaped filter.
Description
Technical field
The utility model relates to a kind of motor car engine, relates in particular to the camshaft hydraulic control valve in the VVT system on a kind of motor.
Technical background
VVT is an english abbreviation, and full name is " Variable Valve Timing ", and the Chinese meaning is " Variable Valve Time ".The VVT system is mounted on the vehicular engine, and it mainly partly is made up of sensor, ECU and camshaft hydraulic control valve, controller etc.ECU has stored optimal valve timing parameter value, feedback informations such as crankshaft position sensor, intake manifold air pressure probe, throttle position sensor, cooling-water temperature sensor and CMPS Camshaft Position Sensor are pooled to ECU and compare calculating with the predefined parameter value, calculate corrected parameter and issue instructions to control camshaft timing hydraulic control valve, control valve is according to the position of ECU command control machine oil groove valve, just change hydraulic flow, signal instructions such as shifting to an earlier date, lag behind, remain unchanged is selected to be delivered on the different oil ducts of VVT controller.
The VVT system is a hydraulically powered precision optical machinery mechanism, requires very high to the turbidity test of machine oil.If there are foreign material to enter the VVT oil pocket, just might make VVT work unstable, slow in reacting with machine oil.Sealability descends in the VVT, even makes the VVT internal rotor stuck.In order to prevent that the booty in the engine motor oil from entering vvt mechanism, generally in the nearly angle of VVT chamber oil-feed oil circuit, filtrating equipment is installed.This filtrating equipment mostly is installed on the engine body, and the whole structure of motor is not compact, and needs specially installation and processing hole slot for this reason, processed complex.Sometimes also may therefore increase the design difficulty of motor oil duct.
Summary of the invention
For overcoming the existing above-mentioned defective of VVT system on the existing vehicular engine, the purpose of this utility model is to provide the camshaft hydraulic control valve in a kind of motor VVT system of new structure, the VVT system that has this hydraulic control valve is assembled on the motor, not needing outside, the outside of motivation body installs filtrating equipment additional again, can make the motor compact overall structure, do not need because the external filter on the motor, and on motor the installation and processing hole slot, process easyly, simplified the design of motor oil duct.
Above-mentioned purpose of the present utility model mainly solves by the following technical programs: the camshaft hydraulic control valve in a kind of motor VVT system, comprise valve body and valve pipe, described valve pipe is located in the cylinder head of motor, be located at oil duct in the cylinder head in order to communication, it is characterized in that: described valve pipe is provided with some oilholes, this oilhole comprises oil inlet hole and oil outlet, described oilhole staggers mutually in the position that the valve tubular axis makes progress, and the position of oil inlet hole is provided with the filter of round shell-like on the valve pipe.The position of oil inlet hole is provided with filter on the valve pipe, and the impurity in the filtering machine oil has so effectively guaranteed the working stability of whole VVT system.In addition, because filter and valve pipe be located in the cylinder head jointly, and do not need to be provided with external filter on cylinder head, compact overall structure need not increase oil duct in addition on cylinder head again, and cylinder head is processed, simplicity of design, and is easy for installation.
As preferably, described filter is a metal screen.
As preferably, the two ends of described metal screen are provided with O-ring seals.
As preferably, described O RunddichtringO one cast is formed on the end of metal screen.
As preferably, described oil outlet comprises first oil outlet and second oil outlet, wherein on the position of first oil outlet and the cylinder head set advance angle cavity to pass in and out the oil inlet and outlet of oil duct corresponding, it is corresponding that set phase lag cavity passes in and out the oil inlet and outlet of oil duct on the position of described second oil outlet and the cylinder head, and the oil outlet of set main oil gallery is corresponding on the position of described oil inlet hole and the cylinder head.
Therefore, the beneficial effects of the utility model: because the position of oil inlet hole is provided with filter cylindraceous on the valve pipe, and be assembled in the cylinder head with the valve pipe, both guaranteed the cleaning of the working medium in this VVT system, improved the working stability of VVT system, help motor and be in rational working state, simultaneously, also make the compact structure of whole VVT system, be difficult for because of and motor on other component between interfere phenomenon inconvenience and assemble, need not increase oil duct in addition again on cylinder head, cylinder head designs, processing is easy.
Description of drawings
Accompanying drawing 1 is that the utility model hydraulic control valve is assemblied in the structural representation in the engine cylinder cap, at valve Guan Shangwei fixed filter;
Accompanying drawing 2 is structural representations of cylinder-shaped filter;
Accompanying drawing 3 is to have filter on the valve pipe and be assemblied in to analyse and observe the partial structurtes schematic representation in the cylinder head.
Embodiment
As can be seen from Figure, camshaft hydraulic control valve in the utility model motor VVT system is located on the cylinder head 9 on the engine cylinder 11, its structure comprises valve body 1 and valve pipe 2, this valve pipe 2 is provided with three oilholes, i.e. first oil outlet 3, second oil outlet 8 and oil inlet hole 6, the axial position of these three oilholes on valve pipe 2 staggers mutually.By three above-mentioned oilholes, valve pipe 2 can link up that main oil gallery 7, the advance angle cavities be located in the cylinder head 9 pass in and out oil duct 4, phase lag cavity passes in and out oil duct 5 and oil return oil duct 10, and the arrow in each oil duct is represented the flow direction of machine oil in oil duct.
The position of oil inlet hole 6 is provided with a filter cylindraceous on valve pipe 2, and this filter is made of metal screen 12 and two O-ring seals 13 being located at metal screen 12 two ends.It is the two ends of one castable at metal screen 12 that described metal screen covers 6, two O-ring seals of oil inlet hole 13.It is corresponding that set advance angle cavity passes in and out the oil inlet and outlet of oil duct 4 on the position of the first above-mentioned oil outlet 3 and the cylinder head 9, and first oil outlet 3 passes in and out oil duct 4 with advance angle cavity and communicates; It is corresponding that set phase lag cavity passes in and out the oil inlet and outlet of oil duct 5 on the position of second oil outlet 8 and the cylinder head 9, and second oil outlet 8 passes in and out oil duct 5 with phase lag cavity and communicates; The position of oil inlet hole 6 is corresponding with the position of being located at main oil gallery 7 oil outlets in cylinder head 9 and the cylinder block 11, and oil inlet hole 6 communicates with main oil gallery 7; Cavity in oil return oil duct 10 and the valve pipe 2 communicates.Above-mentioned oilhole and the status requirement of being located at the oil duct hydraulic fluid port in the cylinder head 9 make that the machine oil in this VVT system can keep smoothness preferably in flow process.
