Abstract
The invention relates to a filtering structure of an engine valve pushing part oil control valve. The oil control valve is arranged on an oil control valve installation base in an inserted mode. An oil supply channel flows into the oil control valve through the oil control valve installation base and is subjected to outflow control through the oil control valve. The oil control valve installation base is installed on a cylinder head. The oil control valve is provided with an electromagnetic element used for controlling oil ways. The electromagnetic element of the oil control valve is arranged to be close to the outer wall of the cylinder head and keep a distance away from the outer wall of the cylinder head, and is arranged in the direction approximately facing a cylinder block. A filter is arranged on the oil supply channel of the oil control valve installation base and is located in the upstream relative to the oil control valve. When the filter needs to be repaired, only a closing screw needs to be opened to take the filter out of a containing part of a connecting base part, and according repair action on the filter can be conducted under the condition that the oil control valve installation base and the oil control valve do not need to be dismounted. On the one hand, the precision of the oil control valve can be maintained, and on the other hand, the usability of the oil control valve can be better ensured.
Description
Technical field
The present invention is the depuration structure about a kind of engine valve pushing piece oil controlling valve, espespecially a kind of the lubricating oil fluid entered in oil controlling valve can be carried out filtering action and can the maintenance action of convenient filter to guarantee the depuration structure of the engine valve pushing piece oil controlling valve of oil controlling valve usability.
Background technology
For the variable lift valve of engine can be operated swimmingly, therefore engine can be installed with the oil controlling valve 1 of a valve impeller that can provide lubricating oil.
As it is shown in figure 1, application artificially allows this oil controlling valve stably operate, then create TWI452205 " the oil controlling valve structure of the variable lift of engine valve " Patent Case.This oil controlling valve 1 its primarily serve the purpose of control this lubricating oil flow, and then make valve impeller accurately to operate, but lubricating oil circulates in engine, after a period of time, how I haven't seen you for ages is accumulated some foreign material, foreign material contained by this lubricating oil are once entering in this oil controlling valve 1, due to the electronic component that this oil controlling valve 1 is quite accurate, therefore very easily cause this oil controlling valve 1 to lose effect and cannot operate, in turn result in engine and cannot do the action of variable lift.
Therefore, how to carry out the action of filtering for entering the lubricating oil in oil controlling valve 1, to guarantee that this oil controlling valve 1 can normally operate, be vehicle dealer problem urgently to be resolved hurrily.
Summary of the invention
Present invention is primarily aimed at the depuration structure that a kind of engine valve pushing piece oil controlling valve is provided, be mainly and the lubricating oil fluid entered in oil controlling valve is carried out filtering action, and can the maintenance action of convenient filter, guarantee the usability of oil controlling valve.
The present invention is for reaching above-mentioned purpose, the technical way adopted is in that: provide the depuration structure of a kind of engine valve pushing piece oil controlling valve, this oil controlling valve is to be inserted in an oil controlling valve mounting body, one confession oil duct is to flow into oil controlling valve by oil controlling valve mounting body, undertaken flowing out control by oil controlling valve again, this oil controlling valve mounting body is to be installed on cylinder head, this oil controlling valve is provided with the electromagnetic component of oil circuit control, the electromagnetic component of this oil controlling valve be close to cylinder head outer wall and and cylinder head outer wall keep interval, and the direction being approximately towards cylinder block is arranged, one filter, it is be arranged on the confession oil duct of oil controlling valve mounting seat, and be positioned at the upstream end for oil duct compared to oil controlling valve.
Effect that the present invention can be reached by above-mentioned technological means is in that: have a holding part by this oil controlling valve mounting seat in this connection seat portion is extended towards side, this holding part connects the confession oil duct in this connection seat portion, this holding part is provided with closing screw relative to the side of this confession oil duct, it is provided with metal seal between this closing screw and this holding part, this closing screw court enters oil duct and is convexly equipped with top splenium, it is available for a filter in this holding part to plug, by this filter, the lubricating oil fluid entered in oil controlling valve is carried out filtering action, thereby guarantee that this oil controlling valve can normally operate；Additionally, when this filter is intended to keep in repair, only need to open this closing screw can be taken out in the holding part in this connection seat portion by this filter, therefore can in without by under this oil controlling valve mounting seat and oil controlling valve disassembly status, the maintenance action of device can be filtered, thereby can maintain the elaboration of this oil controlling valve on the one hand, more can ensure that the usability of this oil controlling valve on the other hand.
