Abstract

The utility model discloses a kind of engine cooling nozzle, which includes the nozzle body and the nozzle bolt; the nozzle bolt is fixed to the engine cylinder; the nozzle bolt has a oil inlet path connected to the auxiliary oil oath of the engine cylinder; the oil outlet path of the nozzle bolt is connected to the oil outlet mouth of the nozzle body; at the joint place between the oil inlet path and the oil outlet path of the nozzle bolt is installed a pressure control valve. When the output power of the engine is small, the pressure control valve closes, the cooling nozzle stops spraying oil and the oil pressure in the oil path is not reduced, ensuring that other parts of the engine are fully lubricated; when the output power of the engine is large, the pressure control valve opens, and the cooling nozzle sprays oil.

Description

The engine cooling nozzle
Technical field
The utility model relates to engine cooling nozzle technology field, relates in particular to a kind of cooling jet that is used for the cooled engine piston.
Background technique
Existing cooling jet is as long as engine operation is with regard to commencement of fuel injection.For motor, when its output power hour, there is no need piston is cooled off, have only when its output power is big, just need to cool off.Cold oil will enter into piston needs certain pressure, so just can make piston obtain cooling off more fully.But, the output power of motor hour, the engine oil pressure in the motor oil duct is also less, if this moment nozzle also in oil spout, will reduce the engine oil pressure in the oil duct, make other component of motor can not sufficient lubrication.
The model utility content
Technical problem to be solved in the utility model is: a kind of engine cooling nozzle is provided, with solve engine output less, when piston need not to cool off, cooling jet is still in oil spout, thereby the engine oil pressure in the reduction oil duct causes the lubricated sufficient inadequately technical problem of other component of motor.
For solving the problems of the technologies described above, the technical solution of the utility model is: the engine cooling nozzle, comprise nozzle body and nozzle bolts, described nozzle bolts is fixedlyed connected with engine cylinder, described nozzle bolts has oil inlet passage that can be communicated with the secondary oil duct of engine cylinder and the oil discharge passage that can be communicated with the oil outlet of nozzle body, at the oil inlet passage and the place of connection of oil discharge passage of described nozzle bolts a pressure controlled valve is installed.
Described pressure controlled valve preferentially is installed in the oil inlet passage of nozzle bolts.
Described pressure controlled valve can be realized by following concrete structure: comprise one with suitable plunger and the spring that axially relies on described plunger of the oil discharge passage shape of nozzle bolts.
When engine output hour, engine oil pressure in the oil duct is lower, because the effect of spring, pressure controlled valve is in closed condition, the oil inlet passage of nozzle bolts is not communicated with oil discharge passage, not oil spout of cooling jet this moment, the engine oil pressure in the oil duct does not reduce, thereby has guaranteed the sufficient lubrication of other component of motor.When engine output was big, the engine oil pressure in the oil duct increased, and makes length of spring compressed, and plunger moves, and pressure controlled valve is opened, and the oil inlet passage of nozzle bolts is communicated with oil discharge passage, the cooling jet oil spout.Adjust the rigidity of spring, can adjust the cracking pressure of pressure controlled valve.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model embodiment's a longitudinal sectional view.
Embodiment
The engine cooling nozzle, as shown in drawings, comprise nozzle body 5 and nozzle bolts 1, described nozzle bolts 1 is fixedlyed connected with engine cylinder, described nozzle bolts 1 has oil inlet passage that can be communicated with the secondary oil duct of engine cylinder and the oil discharge passage that can be communicated with the oil outlet of nozzle body 5, at the oil inlet passage and the place of connection of oil discharge passage of described nozzle bolts 1 pressure controlled valve is installed.
Described pressure controlled valve is installed in the oil inlet passage of nozzle bolts 1.
Described pressure controlled valve comprise one with suitable plunger 3 and the spring 4 that axially relies on described plunger of the oil discharge passage shape of nozzle bolts 1, retaining washer 2 is limited in spring 4 in the oil inlet passage.
