Abstract
The utility model relates to a cooling nozzle assembly of a diesel comprising a nozzle bolt, a nozzle body and an injection pipe; the nozzle bolt is provided with an oil inlet channel communicated with the oil way of a cylinder body of the diesel and an oil outlet channel communicated with the oil outlet port of the nozzle body; a pressure control valve used for controlling the oil ejection of the diesel is arranged on the communicating location of the oil inlet channel and the oil outlet channel of the nozzle bolt; the pressure control valve comprises a spherical piston matched with the shape of the oil outlet channel, a pressure spring against the spherical piston axially and a fixed gasket used for limiting the pressure spring in the oil inlet channel; the welder of the injection pipe is arranged on the nozzle body and the end of the injection pipe is provided with a gentle smooth necking. The cooling nozzle assembly has the advantages that the cooling nozzle does not eject the oil when the output power of the diesel is smaller and rotates at an idle speed or low speed, thus avoiding energy waste; besides, the cooling nozzle assembly has a reasonable and simple structure, is convenient and practical as well as is suitable for being popularized and applied.
Description
(1) technical field
The utility model relates to the parts and components of diesel engine technical field, relates in particular to a kind of diesel engine assembly of cooling jet that is used to cool off diesel engine piston.
(2) background technique
Existing diesel engine cooling jet is generally open type, does not have pressure controlled valve on its oil duct, as long as diesel engine work just begins to spray cooling machine oil.For diesel engine, when its output power hour, there is no need piston spray machine oil is cooled off, therefore unnecessary oil spout when diesel engine idling and slow-speed of revolution operation, caused waste, and the oil pressure when causing the diesel engine idling and the slow-speed of revolution easily is on the low side, makes other component of diesel engine can not sufficient lubrication.
(3) summary of the invention
The utility model is during for the diesel engine idling that solves prior art and exist and the slow-speed of revolution, nozzle still sprays machine oil, thereby reduce the engine oil pressure in the diesel engine oil duct, cause the lubricated technical problem fully inadequately of other component of diesel engine, provide a kind of rational in infrastructure and only when needs are lubricated, open, convenient and practical diesel engine assembly of cooling jet.
The utility model is realized by following measure: a kind of diesel engine assembly of cooling jet, comprise nozzle bolts, be fixed with the nozzle body of locating stud and be fixed on injection pipe on the nozzle body, described nozzle bolts is fixedlyed connected with cylinder of diesel engine, described nozzle bolts has oil inlet passage that is communicated with the cylinder of diesel engine oil duct and the oil discharge passage that is communicated with the oil outlet of nozzle body, it is characterized in that: the oil inlet passage of described nozzle bolts is provided with the pressure controlled valve that is used to control diesel engine fuel injecting with the place of connection of oil discharge passage.
Pressure controlled valve described in the utility model is installed in the oil inlet passage of nozzle bolts.
Pressure controlled valve described in the utility model comprise the spherical plunger suitable with the oil discharge passage shape, axially rely on spherical plunger stage clip, be used for stage clip is limited in retaining washer in the oil inlet passage.
Injection pipe described in the utility model is welded on the nozzle body, and injection pipe mouth of pipe end is provided with one section mild reducing, and jet pressure is increased, and makes piston lubrication more abundant.
Working principle of the present utility model: when the diesel engine output power is less when being in the idling or the slow-speed of revolution, engine oil pressure in the oil duct is low, because the effect of stage clip, pressure controlled valve is in closed condition, the oil inlet passage of nozzle bolts is not communicated with oil discharge passage, this moment, cooling jet did not spray machine oil, and the engine oil pressure in the oil duct does not reduce, thus the engine oil pressure when having guaranteed the diesel engine idling and the slow-speed of revolution and the sufficient lubrication of other component of diesel engine.When the diesel engine output power was big, the engine oil pressure in the oil duct increased, and made stage clip compress, and spherical plunger moves, and pressure controlled valve is opened, and the oil inlet passage of nozzle bolts is communicated with oil discharge passage, cooling jet ejection machine oil.Adjust the rigidity of stage clip, can adjust the cracking pressure of pressure controlled valve.
The beneficial effects of the utility model:
1. the diesel engine output power is less when being in the idling or the slow-speed of revolution, and cooling jet does not spray machine oil, can not cause energy waste.
2. because engine oil pressure is controlled better, and utilization ratio is higher, makes diesel engine can select lower-powered oil pump, save cost, alleviated the weight of diesel engine; Little, the lightweight oil pump of power can also reduce the engine oil consumption of diesel engine.
3. rational in infrastructure, simple in structure, convenient and practical, suitable applying.
