Abstract
The utility model relates to a piston cooling spraying nozzle bolt, which is provided with a hollow bolt body, an oil inlet opening communicated with a cylinder block oil duct of a diesel engine and an oil outlet hole communicated with the cooling spraying nozzle which are arranged at the lower part of the bolt body, a pressure-regulating valve body and a spring which are installed in the cavity of the bolt body, and a valve seat installed at the upper end of the bolt body. When the diesel engine is started to work, and when the pressure of the oil inlet opening achieves a set value, the pressure-regulating valve body makes movement and compresses the spring, in order to open the oil outlet hole, and engine oil enters into the piston cooling spraying nozzle and is sprayed out. The piston is cooled and lubricated timely, in order to guarantee the normal work and the service life of the diesel engine.
Description
Technical field
The utility model relates to the piston cooling nozzle device that is used on the motor, particularly relates to a kind of piston cooling nozzle bolt that has the pressure regulator valve structure.
Background technique
To the process of work, engine oil pressure is most important in starting for diesel engine.If the oil duct engine oil pressure of diesel engine is on the low side, piston cooling nozzle can not oil spout, will cause diesel engine to be drawn watt.The piston cooling nozzle of existing diesel, be to be installed in the body of diesel engine by bolt, and the control spool is not set generally on the piston cooling nozzle bolt, like this under low engine speed, diesel engine piston often can not get well lubricated, influences the proper functioning and the working life of diesel engine.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of piston cooling nozzle bolt that has the pressure regulator valve structure is provided, and draws because of oil duct inner engine oil pressure is on the low side watt to prevent diesel engine.
The utlity model has a hollow bolt body, it is installed in the diesel-engine body, be used for fixing the installation piston cooling nozzle, its structural feature is to have filler opening that communicates with the cylinder of diesel engine oil duct and the oil outlet that communicates with cooling jet in body of bolt bottom, pressure regulation valve body and spring are installed in body of bolt cavity, valve seat are installed in body of bolt upper end.
At diesel engine starting when working, when filler opening pressure reaches setting value, motion of pressure regulation valve body and pressure spring, cause oil outlet to be opened, machine oil enters piston cooling nozzle and outwards sprays, in time piston is lubricated and cools off, thereby prevent that diesel engine from drawing because of oil duct inner engine oil pressure is on the low side watt, guarantee the proper functioning and the working life of diesel engine.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1, shows overall structure of the present utility model.
Embodiment
The accompanying drawing illustrated embodiment the utlity model has a hollow bolt body 1 that has longitudinal hole, and it is installed in the body of diesel engine by screw thread, is used for fixing the installation piston cooling nozzle.Have the filler opening 6 that communicates with the cylinder of diesel engine oil duct in the bottom of the body of bolt 1, have the circumferential oil outlet that communicates with cooling jet 5 at the middle part of the body of bolt 1, in the cavity of the body of bolt 1, be movably installed with pressure regulation valve body 2 and be pressed in spring 3 on the pressure regulation valve body 2, the valve seat 4 that spring 3 is pushed down is installed in the body of bolt 1 upper end.
Under low engine speed, when filler opening 6 pressure reach setting value, pressure regulation valve body 2 overcomes spring 3 pressure and moves upward, and oil outlet 5 is opened, and machine oil enters piston cooling nozzle by filler opening 6 by oil outlet 5 and outwards sprays, and piston is cooled off and lubricated.
