According to the invention, the cooling unit (3) and the valve plate (4) are fully integrated in the cylinder head (1) in a monolithic design.
Description
Technical field
The present invention relates to a kind of cylinder cap for compressor, the cylinder cap has：The cooling unit arranged thereon, for cold
But cylinder cap；And valve plate.
Background technology
Subsystem of the modern Commercial car used in rail transit or road traffic equipped with multiple consumption of compressed air
System.The service braking device and air spring for for example being run with compressed air belongs to this subsystem.By compressed air supply
Device is realized being provided with compressed air to this pressure air consumer, and the compressed air feedway includes compressor.Ring
Border air by compressor suck, compression and used in consumer before, compressed air feedway other constitute
Impurity is cleaned in part, for example oil and water.
Due to the requirement of the sustainable growth to efficiency and the compressed air discharge temperature of restriction, contemporary compressor is to structure
Part, such as valve plate, cooling unit and cylinder cap propose high request.These components are negative due to the heat load from compressor and machinery
Carry and be subject to strong load.According to commonly known prior art, valve plate, cooling unit and cylinder cap are sealed against each other and screw thread connects
Connect.Refrigerating function is integrated in cylinder cap and abandons using single cooling unit by individual solutions modification.
In the field for the dump valve of piston compressor, from commonly known prior art automatic reed is learnt
Valve.The leaf valve either fix or can rise along the guide of both sides by side.Leaf valve is generally riveted on to be had
On the valve plate of through flow hole, and including upper arrester, spring element and valve block.
The content of the invention
The present invention task be：The cylinder cap of the optimization for compressor is realized, the cylinder cap contributes to improving compressor
Performance, and reduce risk of leakage.
From the cylinder cap of preamble according to claim 1, the feature of binding characteristic part is solving for the task.
The favourable expansion scheme of the present invention draws from following dependent claims.
According to the present invention, cooling unit and valve plate are completely integrated in cylinder cap in unitary construction mode.In other words, cylinder cap had been both
Include valve plate again including cooling unit and be configured to solid memder.Advise in Technology, in unitary construction mode according to disappearing
Losing mold technique (Lost-Foam-Verfahren) or increasing material technique (generatives Verfahren) manufacture includes that cooling is single
Unit and the fully-integrated cylinder cap of valve plate.According to increasing material manufacturing technique --- such as rapid prototyping (Rapid Prototyping),
Stereolithography (Stereolithografie), laser sintered (Lasersintern) etc. --- manufacture overall cylinder cover is especially suitable
In prototype and small lot batch manufacture.Lost foam casting process is proposed to be used in middle batch and more produces in enormous quantities.
Compared with traditional casting technique, the more complicated geometry of lost foam casting process permission and bigger configuration are certainly
By spending.These configuration advantages realize the new configuration for overall performance of the air guide path in cylinder cap and aquaporin, utilize
The new configuration reaches the performance boost of compressor overall system.
By integrated cylinder cap, coldplate and valve plate and by reducing interface due to unitary construction mode, not only
The risk of blow-by is avoided completely, also saves at least two sealing devices, in the case of the non-integral configuration of cylinder cap, institute
State at least two sealing devices to be arranged between cylinder cap and coldplate and between coldplate and valve plate.Material is saved and weight
Save and also realized by cancelling support structures, because by integrated cylinder cap, cooling unit and valve plate, saving cylinder cap with cooling
Between unit or between cooling unit and valve plate stitching position, and therefore in this scope also without passing through
Threaded connection provides continuous surface extruding.What is can not ignored also has following process and assembling expense reduction and due to few
The number of components cost saving potential.
Preferably, at least two recessed cage structures are on the face towards compressor of cylinder cap, for receiving a row respectively
Go out valve cell.The release valve unit as single insertion part allow with the material of fully-integrated cylinder cap independently, phase
To freely selecting material.Because load peak just occurs in the region of dump valve, can pointedly use here
More there is the raw material of resistance capabilities, the raw material is enough for the requirement of local.
Especially preferably, the release valve unit is made to be solded into or be threaded in the respective recess on cylinder cap.
Laser welding process is particularly suited for that release valve unit is solded in the respective recess on cylinder cap.Advantage is especially quick
With accurate processing, extraordinary radiating and very high sealing.Release valve unit is threaded into each on cylinder cap
From recess in replacement probability provide material pairing more flexible selection.
It is also preferable that：The release valve unit has valve plate, and the valve plate is arranged into respective recessed on cylinder cap
In portion.Additionally, at least two guide pins are arranged on valve plate, for axially directed at least one valve block.Additionally, it is described extremely
Substantially abreast be disposed with blocking member with valve plate on few two guide pins, the blocking member construct for it is described at least
The stopper section of one valve block.Arrange at least one spring element between at least one valve block and blocking member in the axial direction
Part, for the return of at least one valve block.When pressure is applied, at least one valve block resists the pressure of spring element
Rise from valve plate.Here, at least one valve block is remained at any time parallel to valve plate, air optimization is achieved in
Flow out on ground.
Description of the drawings
The preferred embodiments of the present invention are described in detail below with reference to two accompanying drawings and further improvement of the present invention is arranged
Apply.It illustrates：
The side view of Fig. 1 compressors of the invention, with cylinder cap and the piston shell cut open,
Fig. 2 according to the three-dimensional view of the cylinder cap of the invention of Fig. 1, and
The three-dimensional view of Fig. 3 release valve units of the invention.
Specific embodiment
According to Fig. 1, compressor of the invention 2 includes piston shell 13 and with fully-integrated cooling unit 3
With the overall cylinder cover 1 of valve plate 4.Compressor 2 is driven by axle 14.Piston shell 13 is broken away in the vicinity of cylinder cap 1 such that it is able to
See piston chamber 15.In the inside of piston chamber 15, the piston being not shown here moves up and down in the axial direction.
According to Fig. 2, fully-integrated overall cylinder cover 1 has two recess 6a, 6b on the face 5 towards compressor 2, uses
In one release valve unit 7a, 7b being not shown here of reception respectively.Described two recess 6a, 6b are used as from compressor 2
The discharge chambe being not shown here compressed air outlet.Additionally, the entrance 16a-16h of 8 input airs, for here
6 of unshowned cylinder bolt opening 17a-17f and 2 of ESS pistons for being not shown here wear mouthful 18a, 18b structure
Make on the face 5 towards compressor 2.Therefore, the cylinder cap 1 is applied to ESS (energy conserving system, Energie Saving
System compressor 2).
