It is equipped with spring 4, spool 4 is placed in spool bore 107；The lower end surface of spool 4 presses on spring 5, and upper surface withstands on cylinder cap 1
On lower end surface, spool guide rod 15 is inserted into spool pin hole 110, and the both ends of spool guide rod 15 are led in spool guide groove 108 with spool
Slot 108 is guiding, and spool 4 can be moved up and down by spool guide rod 15 along the guiding of spool guide groove 108 in spool bore 107；?
Be additionally provided with spool return flow line 103 on spool 4, the setting open at one end of spool return flow line 103 on 4 upper surface of spool simultaneously
It is connected always with cylinder body upper end return flow line 1002；Switch valve is arranged on 1008 section of cylinder body flow-guiding channel and cylinder body upper end
Between return flow line 1002 and cylinder body lower end return flow line 1011, the spool 4 of switch valve is divided into cylinder body flow-guiding channel 1008
Cylinder body flow-guiding channel front end and cylinder body water conservancy diversion circulation passage rear end, for controlling opening or disconnecting for cylinder body flow-guiding channel 1008；
In order to easy to process, technique upper cylinder body flow-guiding channel 1008 is penetrated through in 3 diametrical direction of cylinder body, in two cylinder body flow-guiding channels 1008
One end close to external cylindrical surface is provided with plug 16, prevents liquid leakage；Since spool reflux is logical in the cooling duct of liquid feeding side
Liquid in road 1003 is low pressure liquid, and spool 4 is pushed under the action of spring 5 and moved up, and spool 4 moves up, cylinder body flow-guiding channel
1008 connect with spool split channel 1009, shunt from the liquid distributed into round 101 through cylinder cap split channel 1005, cylinder body
Channel 1007,1008 front end of cylinder body flow-guiding channel, spool split channel 1009,1008 rear end of cylinder body flow-guiding channel enter liquid collecting
Main shaft 14 and 10 coupling part of piston shoes, 11 position of collar bush are cooled down in pond；The other end of spool return flow line 1003 is opened
Mouth is arranged on the cylindrical surface of spool 4, and when the switch valve core 4 in cooling duct opens (spool moves up), spool reflux is logical
Road 1003 and cylinder body lower end return flow line 1011 are connected, and the liquid of collecting tank lower part is successively through spindle carrier diversion trench 1004, cylinder
Body lower end return flow line 1011, spool return flow line 1009, cylinder body upper end return flow line 1002, cylinder cap return flow line 1001 are flowed back
In to liquid feeding side into round 101, and it is inhaled into the operating room 1006 of feed liquor；Since spool returns in the cooling duct of drain side
Liquid in circulation road 1003 is highly pressurised liquid, and highly pressurised liquid push the spring 5 is compressed, and spool 4 moves down in spool bore 107,
Spool 4 is closed, so that cylinder body flow-guiding channel 1008 be made to close, (spool shunts circulation road 1009 and do not connect with cylinder body flow-guiding channel 1008
It is logical), spool return flow line 1003 and cylinder body lower end return flow line 1011 disconnect, and drain side cooling duct blocks.
The course of work of this patent cooling body is:
The rotation of main shaft 14 drives turntable 9 and piston 8 to rotate, and main shaft 14 rotates 360 degree, and the operating room Liang Ge 1006 carries out respectively
Primary completely feed liquor and discharge opeing process；As main shaft continues to rotate, the operating room Liang Ge 1006 alternately feed liquor and drain
Journey.
When ball pump rotates forward, feed liquor makes to switch into the spring 5 below the switch valve in the cooling duct where round 101
The spool 4 of valve jacks up, and the cylinder body flow-guiding channel 1008 on spool split channel 1009 and cylinder body 3 on spool 4 is connected, spool 4
On spool return flow line 1003 and cylinder body lower end return flow line 1011 connect, be diverted to coolant liquid into round 101 from feed liquor
Body, it is logical that cooling liquid is successively set cylinder cap split channel 1005, cylinder body split channel 1007, cylinder body water conservancy diversion on cylinder cap 1
Enter collecting tank after road 1008, spool split channel 1009；Liquid in collecting tank is successively set the master on spindle carrier 6
Bracing strut diversion trench 1004, cylinder body lower end return flow line 1011, spool return flow line 1003, cylinder body upper end return flow line 1002 and
Enter the side behind cylinder cap return flow line 1001 in the downstream passage into after throttling in round 101, in company with into the liquid in apocenosis passage
Body is inhaled into operating room 1006, to form cooling cycle in liquid feeding side cooling duct；At this point, because drain is into round
It is highly pressurised liquid in 101,4 compressed spring 5 of spool moves down to close spool 4, and cylinder body flow-guiding channel 1008 is closed, cylinder body lower end
Return flow line 1011 is not connected to spool return flow line 1009, so cooling logical with the drain side of drain being connected into round 101
Road is closed；
Similarly, it when ball pump inverts, is opened with the switch valve in the cooling duct of reversion feed liquor being connected into round 101,
Cooling cycle is formed, at this point, due to being high pressure with the liquid of drain being connected into round 101, the valve in the cooling duct of drain side
4 compressed spring 5 of core moves down to close spool 4, and the spool split channel 1009 on spool 4 does not connect with cylinder body flow-guiding channel 1008
Logical, spool return flow line 1003 is not connected to cylinder body lower end return flow line 1011, so cold with being connected into round 101 for drain
But channel is closed.
