Embodiment
As shown in Figure 1 and Figure 2, the utlity model has the pressure controlled valve of lubricating function, comprise valve body 1, valve body 1 inner chamber is provided with controls spool 2 and overflow spool 3;
Controlling spool 2 is contained in valve body 1; The front end of controlling spool 2 is provided with bolt 4, and bolt 4 is fixedly connected with valve body 1; The rear end of controlling spool 2 connects the first spring seat 6 by the first spring 5;
Control between spool 2 and the first spring 5 and be provided with pressure regulation circle 7;
The front end cavity 9 of controlling spool 2 is connected with filler opening 11; Controlling spool 2 can move backward under the effect of front end oil pressure; Control spool 2 and be provided with the first oil outlet 12 and the second oil outlet 13; The first oil outlet 12 is connected with radiator by oil pipe; Other component mechanisms such as the second oil outlet 13 and torque-converters, gearbox etc. are connected;
In the time that control spool front end oil pressure is the first pressure P 1, controls spool 2 and move backward, until filler opening 11 is connected with the first oil outlet 12; In the time that control spool front end oil pressure is the second pressure P 2, the second oil outlet 13 is opened; Wherein, first pressure P 1 < the second pressure P 2;
The second oil outlet 13 is connected with the front end of overflow spool 3 place cavitys; The front end edge of overflow spool 3 place cavitys is circumferentially formed with oil-return groove 14; The rear end of overflow spool 3 connects the second spring seat 10 by the second spring 8;
In the time that the oil liquid pressure in the second oil outlet 13 is greater than the elastic force of the second spring 8, oil liquid pressure moves overflow spool 3 backward, until the second oil outlet 13 is connected with oil-return groove 14, now the fluid in the second oil outlet 13 enters oil-return groove 14, thereby make the fluid amount in the second oil outlet 13 controlled, to play pressure regulation effect.
Working principle of the present utility model is as follows:
Fluid enters from filler opening 11, promotes to control after spool 2 to move filler opening 11 is connected with the first oil outlet 12, and fluid enters radiator through the first oil outlet 12 and oil pipe and carries out cooling;
In the time controlling spool 2 and cause due to fluid overfill that pressure is excessive herein, part fluid starts to push the first spring 5, Oil shocking is on pressure regulation circle 7, because pressure regulation circle 7 is connected with the first spring 5, so under oil pressure effect, control spool 2 and start to move backward, filler opening 11 is communicated with the first oil outlet 12, and pressure is thereupon adjusted;
When fluid is undertaken after cooling processing by radiator, fluid starts to reflux, and fluid is back in lubricant reservoir, then enters other component mechanisms such as torque-converters, gearbox through the second oil outlet 13, and said mechanism is lubricated;
When the fluid of the second oil outlet 13 is filled too fast while causing that pressure rises sharply herein, after starting, moves by the second spring 8 of overflow spool 3 its inside of extruding, in the time that the front end of overflow spool 3 retreats to oil-return groove 14 position, the oil having more is got back to oil-return groove 14 just in time can regulate high-pressure;
When the fluid flowing out from the second oil outlet 13 completes lubrication operation, fluid all flow in the casing of gearbox and stores.
