Each piston has lateral surfaces or side surface or external diameter (OD) surface 50 (Figure 1A) and upper surface or top surface 52.
Figure 1A shows the piston in the foremost of top dead centre (TDC) position.It is big in tdc position, the lateral part 54 of upper surface 52
Cause flushes with the upper surface 60 of cylinder block 44.Valve board assembly 70 be arranged on the top of surface 60 upper (thering is pad 62 to intervene) and support with
The associated valve module 72 of corresponding cylinder.Following article is further discussed, and valve module 72 each includes forming entrance or suction
The part of valve and the part for forming discharge or outlet valve.Cylinder head 74, which is arranged on valve board assembly top, (has pad 75 to intervene) simultaneously
And close out the discharge pumping chamber 76 connected with outlet 26.
Figure 1A further illustrates piston, and including projecting upwards portion 80, (it has lateral surfaces or side surface to the piston
Or external diameter (OD) surface 82 and upper end or distal end 84), represent to be projected into valve plate in the piston of the portion of projecting upwards up front
Top dead centre state or position in component 70.This helps to minimize head space under top dead centre state to realize improved ensemble stream
It is dynamic.
Example valve board component 70 includes the bottom plate 90 and top plate 92 separated by distance piece.Distance piece can include peripheral panels
94, the periphery of the peripheral panels and valve board assembly coordinates in order to close out pumping chamber 96.Other distance piece 98 can be distributed
In pumping chamber.Following article is further discussed, and pumping chamber 96 is the suction pumping chamber connected with suction inlet 24.For example, inhaling
In the case that entrance 24 is in the motor housing section of casing assembly, suction pumping chamber 96 can be via being cast in casing assembly
In path (not shown) and connected with the inside of motor housing.
Inlet valve includes flexible valve element 120 (Figure 1B), and the flexible valve element is installed circumferentially at each cylinder 42
Between valve board assembly 70 and cylinder block 44.Valve components 120 are formed as thin slice, and the thin slice has lower surface 122 and upper surface
124.At each cylinder, valve components have centre bore, and the centre bore is limited by inner circumferential (internal diameter (ID)) surface 126.Closing
Under closed state, the upper surface 124 of neighbouring inner rim 126 is landed on seating surface 130 (ID valve seats).Exemplary seating surface
130 be the lower surface of valve seat 132, and the upper surface following article of the valve seat further is discussed to form dump valve seating surface.Valve
Internal diameter (ID) surface 134 of seat nearly adapts to the OD surfaces 82 of protuberance 80 under top dead centre state.OD seating surfaces can be with
Formed by a part for the downside of bottom plate 90.
Exemplary suction valve components are typically circular but with two contact pin 135 (Fig. 5) for separating 180 °, and described two
Individual contact pin is placed on crankcase platform for support;And two small contact pin 136, described two small contact pin are used as retainer.
Example valve seat 132 includes upper part, upper part (for example, via press-in cooperation, brazing etc.) peace
It is attached to top plate 92;And low portion, the low portion suspended on through pumping chamber 96 and pass through the correlation in bottom plate 90
The hole 140 of connection.In operation, with piston, stop state is retracted from it, and pressure/suction of reduction makes the folding of valve components 120
Song, i.e., bent intermediate (being similar to U) and supported by two contact pin 135 in the edge of cylinder bore and by contact pin 136 with
The cooperation on the complementary associated surface of the recess in cylinder prevents the valve components.This warpage downwards makes the element
Depart from ID and OD valve base surfaces to allow refrigerant is drawn into cylinder into (hole from suction pumping chamber 96 via port 148
140 annular peripheral part is in the radial outside on external diameter (OD) surface of the low portion of valve seat 132).Bottom out in piston and
After commutation, valve components 120 go back to it and are closed or sealed state, carry out close port 148 so as to engage seating surface.
Valve components 150 (Figure 1B) can be similarly included in dump valve, and the valve components have open mode and closed mode.
Exemplary valve element 150 is spring loads annulation, and the spring loads annulation has lower surface 152, upper surface 154, interior
Footpath (ID) periphery surface 156 and external diameter (OD) periphery surface 158.For valve example valve seat include internal diameter (ID) valve seat and
External diameter (OD) valve seat.External diameter valve seat is formed by the top seating surface 160 of valve seat 132.Exemplary ID valve seats are by inner seat component
166 external diameter periphery surface 164 is formed.Component 166 is pacified in turn in center fastener to valve guide 170, the valve guide
On the top of top plate 92.One or more springs 180 are (for example, the metal coil spring in the block set 182 being retained in guider
Circumference array (for example, each cylinder has three to two ten such springs and block set combination, or eight to ten six springs and sets
Seat combination, illustrated therein is exemplary 12 springs and block set combination) valve components 152 can be made to be biased to its closed mode.
As piston moves upwardly toward its top dead centre state, the pressure in head space eventually exceedes in discharge pumping chamber
Pressure.Now (or being attributed to the biasing of dump valve, after this), discharge valve member 150 will be opened from its closed mode direction
State moves, so as to allow refrigerant to be delivered to from head space in discharge pumping chamber.When piston arrives at top dead centre, dump valve can be again
Secondary closing.
Under this exemplary configuration of dump valve, piston projection 80 includes central recess 200 (Figure 1A), the center
Recess is received when piston approaches top dead centre and adapts to dump valve inner seat component 166 in order to minimize head space.
When piston approaches top dead centre, the gas in the small space of the top of lateral part 54 of upper surface 52 can be driven upwards
It is dynamic.In baseline system, this refrigerant is driven upwardly the lateral surfaces 82 of protuberance 80 and the adjacent I D tables of valve seat 132
Between face 134.The seal in space may cause flow resistance, so as to reduce compressor efficiency.Therefore, Figure 1A is by passage
220 are added to the configuration of baseline piston.Passage extends to upper end 226 from lower end 224.Lower end can substantially form ingress port and (enter
Mouthful) and upper end 226 can substantially form outlet port (outlet) to be moved upwards up in piston described in top dead centre state most
Passed through during the whole stage for flow.Exemplary lower end 224 is to follow protuberance lateral surfaces 82;However, exemplary upper end 226 is
Follow recess 200.Exemplary path 220 is airtight passage (for example, they have complete transverse circumference), and this is different from opening
Passage or groove.Therefore, exemplary path 220 can be by drilling to be formed in the piston of casting.Finally circumferentially about
Piston and cylinder-bore axis 502 distributed one group of exemplary path.Exemplary configuration has four this passages 220 (Fig. 3).It is wider
Scope be 1 to 10 or 2 to 8.
During the later stage moved up, passage lower end 224 can be exposed on above suction valve components and piston
Between the lower section of lateral part 52 of rise surface.The movement further up of piston can be tended to drive some gases to wear upwards
Passage 220 is crossed, so as to leave upper end/outlet 226 and thus flow out dump valve.Prototype test is had shown that in baseline compressor
Rated condition under substantially 1% efficiency improvement.Depending on implementation, embodiment may be configured to offer and be slightly increased
Capacity (or the capacity being potentially slightly reduced).
The exemplary dimensions in each hole are related to 0.5mm diameters and 4.9mm2Sectional area.Exemplary total sectional area (the example of passage
Such as, it is four times in the hole sectional area of example piston) it is 19.6mm2。
When compared with other the similar baseline compressors for lacking hole/passage 220, the pore area carrys out 5% TDC clearances
Volume increase.This may generally reduce overall performance.However, because the influence of improved flowing is more than increased clearance volume
Influence, therefore observed the raising of performance and the reduction of power.It is therefore contemplated that the flowing benefit of hole size is got in return
The clearance volume that can be increased of return of shrink offset, and if Kong Tai great, then can bring the performance of reduction.Small
Size because flow through hole exist flow resistance without provide overall benefit in the case of, there is likely to be lower limit threshold for hole size
Value.
The sectional area in alternative indivedual holes is at least 2.0mm2Or 2.0mm2To 10.0mm2.Alternatively total sectional area is
At least 5.0mm2Or 5.0mm2To 50.0mm2。
Other modifications made relative to baseline compressor are that ventilating opening 300 (Figure 1B) is added into spring block set 182.
In one exemplary variation, baseline spring block set is blind hole, lower periphery surface portion of the blind hole from valve guide 170
302 upwardly extend.Laid against the base portion of blind hole the upper end of baseline spring 180.Exemplary modification addition ventilating opening 300 as compared with
The less coaxial drilling of narrow path, such as diameter, so as to leave the shoulder formed by the peripheral part of the basal surface of baseline block set
Portion 304.Ventilating opening 300 is therefore with upper at the upper surface 314 at block set 182 with lower end 310 and in valve guide 170
End 312.
One or more of some advantages can be obtained by adding ventilating opening 300.Can in terms of the response of dump valve
With by allowing the ventilation of block set 182 to improve.For example, when valve components 150 are driven up from its closed position, in valve components
The steam of side is driven in block set or laterally extruded via circumferential openings 320.This in block set is driven to regard to steam
For aspect, this may cause the back pressure moved up of resistance valve components 150 in block set.Steam is laterally outward driven
For dynamic this aspect, this may also can be related to back pressure, and may cause the steam and the steam from cylinder discharge
Competition.
One of these situations or both can solve by adding ventilating opening.In some embodiments, ventilating opening
The steam initially above valve components 150 can be allowed to be discharged into block set and allow the steam in block set outwards to discharge.
Some embodiments other it is potential the advantages of be related to the flow from cylinder be transferred through block set and ventilating opening.
For example, the essence of spring biasing can be piston discharge stroke certain part or all during, valve components 150 will not be put down
Push up and close the lower end of block set 182.In this case, can be on radial and axial from a part of steam of cylinder discharge
It is delivered to around the OD peripheries 160 of valve components 150 and inwardly and is upward through block set 182 and ventilating opening 300 backward afterwards.
In the case of other, passage or other paths may be provided such that flow even in valve components against stop surfaces flat-top
In the case of can pass through block set and ventilating opening from cylinder.
Independently of the modification discussed above in relation to piston channel 220, prototype test is shown under rated condition substantially
2% capacity increase and 1% EER are improved.
Various other modifications can be carried out to passage 220 or ventilating opening 300.In an example, shown passage 220 can
To be replaced with the circumferential wide-open passage along protuberance or some of open channel and airtight passage mixed forms,
Open channel along the circumferential low portion of protuberance is such as changed into the airtight passage for penetrating recess 200.Another kind becomes
Type may relate to replace the He of helical spring 180 with single wavy spring (for example, space in a ring, such as downwardly open passage)
The array of block set 182.Ventilating opening can upwardly extend from the annular space.
Compressor is used in vapor compression system (e.g., including refrigeration system of deep freezer, air-conditioning, heat pump etc.).
In such systems, compressor can drive cold-producing medium stream to pass through one or more heat rejection heat exchangers along recirculation flow path
With one or more heat absorbing heat exchangers.Basic configuration is related to through heat rejection heat exchanger, expansion gear, heat absorbing heat exchanger and returned
