Abstract
The invention relates to an installation structure for a diesel injector, in particular belongs to the technical field of a power plant. An oil atomizer is arranged in a sealed valve control cabin consisting of a cylinder head, a seal ring and a cylinder cover hood, and is fixed on the cylinder head. The invention is characterized in that: the cylinder head is provided with a high pressure pipe hole; a high pressure pipe joint is connected with the oil atomizer fixed on the cylinder head through the high pressure pipe hole; a sealing element is arranged between the high pressure pipe joint and the high pressure pipe hole. The structure of the invention is simple, compact and rational; the cost of manufacture is reduced; the invention is overhauled conveniently; just the cylinder cover hood is needed to be removed without needing to remove the fuel injection pipe components when the internal components of the cylinder cover hood are maintained; when the invention runs at a low speed, the cylinder cover hood is not required to be covered, and whether the fuel injection pipe joint leaks oil can be observed directly.
Description
Technical field
The present invention relates to a kind of mounting structure of diesel injector, specifically belong to field of power equipment technology.
Background technique
In existing four-valve diesel engine technology, high-pressure oil passage normally is connected to form by Sealing and the oil sprayer that the high-pressure oil pipe that fuel oil is provided to oil sprayer passes on the cylinder head cover, high-pressure oil pipe could be pulled down valve mechanism cover so must dismantle earlier when dismounting or maintenance valve mechanism cover inner body, like this, not only strengthened workman's workload and also might damage high-pressure oil pipe head generation fuel leak accident.Also having a kind of method in addition is to adopt high-pressure oil pipe to be connected to form with the oil sprayer that is fixed on the cylinder head by the transient high pressure oil pocket that is installed on the cylinder head, the quantity that increases number of components and parts like this and increased high pressure sealing face, the risk of leakage that has increased manufacture cost and increased high pressure fuel.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby provide a kind of mounting structure of diesel injector, in the time of need detecting other valve mechanism cover inner bodies such as oil sprayer when diesel engine, need not pull down high-pressure oil pipe again, just can directly keep in repair detection as long as disassemble cylinder head cover, can reach good installation and maintenance effect, save manufacture cost simultaneously and improve the sealing reliability of high-pressure oil passage.
Main solution of the present invention is achieved in that
The present invention mainly adopts the high pressure oil pore that is provided with by the high-pressure oil pipe joint on cylinder head, can allow high-pressure oil pipe connected and be fixed on cylinder head on oil sprayer be connected.
Be provided with Sealing between high pressure oil pore on the described cylinder head and the high-pressure oil pipe joint.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; When dismounting or maintenance valve mechanism cover inner body, only need dismantle valve mechanism cover and no longer need to pull down the high-pressure oil pipe parts; When the low speed running in, need not cover valve mechanism cover, can whether oil leakage phenomenon be arranged the direct observation high-pressure oil pipe.

Fig. 3 structure M-M sectional view of the present invention.
Fig. 4 structure scheme of installation of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly is made up of valve mechanism cover 1, oil sprayer 2, high-pressure oil pipe joint 3, Sealing 4, cylinder head 5, high-pressure oil pipe 6 and seal ring 7, and cylinder head 5 is provided with high pressure oil pore 8.
The present invention is not limited to the above embodiments, also be applicable to and other forms of oil sprayer placed structure in the valve control cab, it can make a kind of maintenance of the interior component of valve cage of diesel engine no longer need to pull down valve mechanism cover, and the installation and maintenance simultaneously of saving manufacture cost are more simple and convenient.
