The liquid of chamber 111 two feed liquors opening 1211 middle flow, prevent liquid is from by the first partition portion 1111, in order to protect
The effect of partition choked flow can be played by demonstrate,proving the first partition portion 1111, and 3 bottom surface of cylinder cap is provided with the muscle being bonded with the first partition portion 1111
Rib.
The utility model also provides a kind of engine liquid cooling cylinder including the engine liquid cold cylinder cylinder body, the outlet
The end in portion 12 is connected with the end cap 2 for covering the second cooling sap cavity.In order to guarantee the leakproofness at end cap 2, in the present embodiment, institute
It states end cap 2 and outlet portion 12 and is provided with corresponding bolt hole inside and outside the second cooling sap cavity 121 with solid by bolt
It is fixed, i.e., the interior outside of the second cooling sap cavity 121 is provided with bolt presses to guarantee its leakproofness.
1 upper end of cylinder ontology is equipped with cylinder cap 3, and the cylinder cap 3 is provided with the water outlet with the first cooling 111 connection of sap cavity
Mouth 31, cylinder cap 3 is for the cooling sap cavity 111 of sealing first and is provided only with water outlet 31 as the first cooling sap cavity 111 and the external world
The unique passage of connection, an only water outlet 31 in the present embodiment, but the quantity of water outlet 31 is not restricted by, in other realities
It applies in example, the quantity of water outlet 31 can be set according to demand.
In order to guarantee the circulation of liquid, the feed liquor opening 1211 is oppositely arranged with water outlet 31, so that the stream of liquid
Dynamic direction does not have too big variation, so that liquid can uniformly be discharged, avoids variation of the partially liq due to circulating direction
Circulation obstacle is caused greatly and is rested on always in cylinder, and radiating efficiency is caused to decline.
In the present embodiment, for the ease of installing cooling line, the water outlet 31 is equipped with water outlet connector 4, the water inlet
Mouthfuls 123 are equipped with water supply connector 6, one end of water outlet connector 4 and water supply connector 6 respectively with 123 screw thread of water outlet 31 and water inlet
Connection, the surface of the other end are provided with convenient for the concavo-convex of piping connection, and the center hole area of water supply connector 6 is about that feed liquor is opened
1.5 times of mouth 1211, this is not particularly limited certainly, and the center hole area of usual water supply connector 6 is greater than feed liquor opening
1211。
In the present embodiment, the pressure in order to prevent in combustion chamber is excessive and influences the work of cylinder, and the cylinder ontology 1 is arranged
There is the bleeder port 112 of connection combustion chamber 11；112 one end connection combustion chamber 11 of bleeder port, other end connection outside air, bleeder port
112 are equipped with pressure reducing valve 5, and when air pressure is excessive in combustion chamber 11, controllable pressure reducing valve 5 is opened to carry out decompression of losing heart, and guarantee vapour
The good operation of cylinder.
When cylinder, coolant liquid enters from water inlet 123, a part of from left side due to the effect in the second partition portion
Feed liquor opening 1211 enter the first cooling sap cavity 111, a part from the lower section of the second cooling sap cavity 121 bypass from right side into
Liquid opening 1211 enters the first cooling sap cavity 111, if liquid enters from water inlet 123 without the effect in the second partition portion 1212
Afterwards, the liquid overwhelming majority directly can be directly entered feed liquor opening 1211 from the left side and avoid the second lower section liquid for cooling down sap cavity 121
Body influences radiating efficiency so that the liquid communication of the lower half of the second cooling sap cavity 121 becomes very poor.And the second partition portion
1212 can make liquid to be open by the feed liquor on right side 1211 when, the liquid of the second cooling 121 lower half of sap cavity must flow
Logical and feed liquor opening 1211 by right side enters the first cooling sap cavity 111.When liquid cools down sap cavity 111 from entering first
When, due to the effect in the first partition portion 1111, liquid can divide or so two-way enters water outlet 31.First partition portion 1111 makes
The liquid of the right and left separates at feed liquor opening 1211, converges at water outlet 31, the first partition portion 1111 can prevent two
The liquid flowing in direction interferes with each other, and influences cooling effect.Due to water inlet 123 be arranged position not necessarily two into
The middle position of liquid opening 1211, the flow rate of liquid of both direction can have non-uniform phenomenon, if without the first partition portion
1111 effect, making liquid, the liquid in the slower direction of flow velocity can be by the fast direction of flow velocity in the first cooling sap cavity 111
Liquid drives, and the liquid flow velocity in the slower direction of flow velocity is sharply declined even and stagnates, largely effects on radiating efficiency.
The cooling sap cavity of the second of the design outlet portion can increase the heat exchange area of coolant liquid Yu cylinder ontology, improve cooling
Efficiency；First partition portion 1111 and the second partition portion 1212 guarantee the circulation of liquid, improve radiating efficiency；And outlet portion and cylinder
Ontology is monolithic construction, so that structure is simple, easily fabricated, production cost is low.
Above embodiments are only to illustrate the technical solution of the utility model and are not intended to limit it, all without departing from this
Any modification of utility model spirit and scope or equivalent replacement should all cover the range in technical solutions of the utility model
It is interior.
