Abstract
A ship cooling nozzle assembly comprises two fuel injection tubes, an oil gathering chamber is formed in the mounting surface on the bottom of the a metal cavity body, the two fuel injection tubes are respectively fixed on two sides of the metal cavity body and are communicated with the oil gathering chamber, four small oil holes are formed in the metal cavity body, two location holes are formed in the mounting face of the metal cavity body, a fixing bolts is arranged on the fuel injection tubes, the fixing bolts abut against the fuel injection tubes, and the fixing bolts are located on the metal cavity body. The oil gathering chamber in the metal cavity body is communicated with a main oil gallery of an engine cylinder block, when power output by a motor is greater, machine oil pressure in an oil-taking gallery is increased, pressure acted on the oil gathering chamber is increased, machine oil in the oil gathering chamber injects through the four small oil holes and acts on a piston cooling nozzle. The cooling nozzle assembly is reasonable in structure and ingenious in design.
Description
Technical field
The utility model relates to marine engine cooling technology field, especially refers to a kind of piston cooling nozzle peculiar to vessel.
Background technique
Along with the power of marine engine is increasing, need to cool off piston crown.At present, the cooling jet on most of motors is ball-valve type, and such cooling jet is when opening, because the pressure valve of cooling jet is spherical, the power that causes acting on the cooling jet changes, so be easy to cause the engine oil pressure fluctuation, affects engine performance.Chinese patent once disclosed a kind of " piston cooling nozzle " (publication number CN1395031Y, open day on February 5th, 2003), structure comprises nozzle body, and nozzle body has entering part, it forms and is engaged in the hole of motor, and in order to accept cooling fluid.Nozzle comprises internal valve, and the piston in the overall pilot hole of spray consists of by guiding and slippage for it.Nozzle comprises head, and it is oriented to updrift side, and is pressed against on the ring-shaped valve seats.The compressed helical spring of piston is pushed ring-shaped valve seats to.Therefore, be used for the high compression engine cooling circuit, and the cooling jet that obtains to some extent internal valve is installed is had longer life expectancy.Chinese patent once disclosed a kind of " diesel engine piston cooling spray nozzle assembly " (China, notification number CN2584845Y, open day on November 5th, 2003), and it has nozzle body, offers oil duct in the nozzle body, and spherical valve core is fitted on the oil duct by compression-spring device.Its usefulness be ball valve.Chinese patent once disclosed " a kind of piston cooling nozzle " (China, notification number CN201786432U, April 6 2011 day for announcing), its structure comprises nozzle body and nozzle plug, the oil discharge passage that the nozzle match has oil inlet passage and is communicated with the nozzle pipe of nozzle body, oil discharge passage and oil inlet passage joint form circular step.Be provided with the plunger that is leaned on by spring top in the oil discharge passage, the shape of plunger and oil discharge passage is adaptive and lean on ring-shaped step.
Summary of the invention
The purpose of this utility model is to provide a kind of piston cooling nozzle assembly peculiar to vessel, and it is rational in infrastructure, and the active force of guarantee effect on piston cooling nozzle is uniform.
For achieving the above object, the solution that the utility model is taked is: a kind of piston cooling nozzle assembly peculiar to vessel, it comprises spray bar, the metallic cavity bottom surface has collection chamber, and two spray bars are separately fixed at the both sides of metallic cavity and are communicated with four little oilholes of metallic cavity distribution with the collection chamber of metallic cavity, be distributed with two positioning holes on the attachment face of metallic cavity, be provided with fixing bolt on the spray bar, fixing bolt withstands spray bar, and fixing bolt is on metallic cavity.
The collection chamber of metallic cavity is communicated with the main oil gallery of engine cylinder-body, when motor was exported larger power, the engine oil pressure in the oil inlet passage increased, and the pressure that acts in the collection chamber increases, machine oil in the collection chamber acts on the piston cooling nozzle from spray bar and four little oilhole ejections.It is rational in infrastructure, designs ingenious.
