本願はデール Ａ．ストレッチの名義で２００６年１０月１７日に出願された、「制御弁組立体」という名称の同時係属米国出願の一部継続出願である。 Cross-reference of related inventions. This is a continuation-in-part of a co-pending US application entitled “Control Valve Assembly” filed October 17, 2006 in the name of stretch.

本発明は、油圧アクチュエータを制御するための制御弁組立体に関し、特に、流体力によって開位置に保持される弁部材を備える制御弁組立体に関する。   The present invention relates to a control valve assembly for controlling a hydraulic actuator, and more particularly to a control valve assembly including a valve member that is held in an open position by a fluid force.

カムの無い内燃機関用弁作動システムは、一般的に、エンジン弁ごとに油圧弁リフタを備えている。油圧弁リフタは一般的に、一対のソレノイドアクチュエータによって選択的に移動させられる二位置弁スプールを各々が備えた一対の制御弁組立体によって制御される。流体圧は、切換弁によって各制御弁に供給され、切換弁は、一対のソレノイドアクチュエータによって制御される二位置弁スプールも備えている。制御弁組立体と切換弁はエンジンコントローラーによって制御されており、弁スプールが一方の位置から他方の位置へ移動するタイミングはエンジンのクランク軸の位置に依存している。制御弁スプールの一つがエンジン弁アクチュエータを制御圧力のかかった貯油槽または低圧の貯油槽に選択的に接続させるので、エンジン弁の各々は選択的に開閉される。制御弁スプールは、エンジン弁アクチュエータごとに、ソレノイドアクチュエータに対して励磁と非励磁を交互に行うことによって、２つの位置に切り替えられる。   A valve operating system for an internal combustion engine without a cam generally includes a hydraulic valve lifter for each engine valve. The hydraulic valve lifter is generally controlled by a pair of control valve assemblies each having a two-position valve spool that is selectively moved by a pair of solenoid actuators. The fluid pressure is supplied to each control valve by a switching valve, and the switching valve also includes a two-position valve spool controlled by a pair of solenoid actuators. The control valve assembly and the switching valve are controlled by an engine controller, and the timing at which the valve spool moves from one position to the other depends on the position of the crankshaft of the engine. One of the control valve spools selectively connects the engine valve actuator to a controlled or low pressure oil reservoir so that each of the engine valves is selectively opened and closed. The control valve spool is switched to two positions for each engine valve actuator by alternately exciting and de-energizing the solenoid actuator.

設計者たちは、システムの全体的な効率を高めるために従来の制御弁組立体の構造を改善し続けている。   Designers continue to improve the structure of conventional control valve assemblies to increase the overall efficiency of the system.

弁開口部と、第１の圧力流路と、第２の圧力流路と、弁本体ランド部と、を備える弁本体が設けられた制御弁組立体が提供される。弁部材は、開位置と閉位置との間の移動のために弁開口部に収容されている。弁部材は、第１の弁部材ランド部と、第２の弁部材ランド部とを備えている。第１の弁部材ランド部と弁本体ランド部は、協働して、第１の圧力流路と第２の圧力流路との間に第１の調量流路を形成し、弁本体ランド部と第２の弁部材ランド部は、協働して、第１の圧力流路と第２の圧力流路との間に第２の調量流路を形成する。第１及び第２の調量流路は、流体が弁本体を通って流れている際に流体力を弁部材に与えるようにされ、それによって弁部材が開位置または閉位置の方へ偏位させられる。   A control valve assembly is provided that includes a valve body that includes a valve opening, a first pressure channel, a second pressure channel, and a valve body land. The valve member is housed in the valve opening for movement between the open position and the closed position. The valve member includes a first valve member land portion and a second valve member land portion. The first valve member land portion and the valve body land portion cooperate to form a first metering flow path between the first pressure flow path and the second pressure flow path. And the second valve member land portion cooperate to form a second metering channel between the first pressure channel and the second pressure channel. The first and second metering channels are adapted to impart fluid force to the valve member as fluid flows through the valve body, thereby deflecting the valve member toward the open or closed position. Be made.

本発明を限定することを意図しない図面を参照すると、図１は、二位置切換弁１２を備えた油圧作動型エンジン弁システム１０を概略的に示している。第１のソレノイド１８が励起されると、圧力入口ポート１４は、制御圧力流路１６への圧力供給路を提供する。第２のソレノイド２０が励起され、第１のソレノイド１８が非励起状態にされると、制御圧力流路１６は、貯油槽の低圧流路２２に接続される。流路１６は、本発明による一対の制御弁組立体２４，２６と連通している。詳細は後述するが、制御弁組立体２４，２６の各々は、少なくとも１つのソレノイドアクチュエータ、より好ましくは２つのソレノイドアクチュエータ２８，３０によって制御される二位置弁部材を備えている。ソレノイドアクチュエータ２８が励起されると、弁部材は、流路１６がエンジン弁アクチュエータ３２，３４と連通する開位置に動く。ソレノイド３０が励起され、ソレノイドアクチュエータ２８が非励起状態にされると、弁部材は、流路１６とエンジン弁アクチュエータ３２，３４との間の連通を阻止する閉位置に移動する。アクチュエータ３２，３４は加圧されるとエンジン弁３６を開け、アクチュエータが減圧されると弁ばね３８がエンジン弁３６を閉じる。   Referring to the drawings that are not intended to limit the present invention, FIG. 1 schematically shows a hydraulically operated engine valve system 10 with a two-position switching valve 12. When the first solenoid 18 is energized, the pressure inlet port 14 provides a pressure supply path to the control pressure channel 16. When the second solenoid 20 is excited and the first solenoid 18 is de-energized, the control pressure channel 16 is connected to the low pressure channel 22 of the oil storage tank. The flow path 16 is in communication with a pair of control valve assemblies 24, 26 according to the present invention. As will be described in detail below, each of the control valve assemblies 24, 26 includes a two-position valve member that is controlled by at least one solenoid actuator, more preferably by two solenoid actuators 28, 30. When the solenoid actuator 28 is energized, the valve member moves to an open position where the flow path 16 communicates with the engine valve actuators 32, 34. When solenoid 30 is energized and solenoid actuator 28 is de-energized, the valve member moves to a closed position that prevents communication between flow path 16 and engine valve actuators 32 and 34. The actuators 32 and 34 open the engine valve 36 when pressurized, and the valve spring 38 closes the engine valve 36 when the actuator is depressurized.

図２は、本発明の一実施形態における制御弁組立体２４，２６の断面図である。図示された実施形態では、制御弁組立体２４，２６は、弁開口部または孔部４２と、第１の圧力流路４４と、第２の圧力流路４６と、弁本体ランド部５０と、を備える弁本体４０を有している。弁部材５２は、閉位置（例えば、図４Ａ参照）と開位置（例えば、図４Ｄ参照）との間の移動のために弁開口部４２に収容されている。一実施形態では、弁部材５２は、既知の磁気特性を持つ弁スプールを有し、ソレノイド２８，３０は励起されると、弁スプールに磁力を与える磁束を生成する。   FIG. 2 is a cross-sectional view of control valve assemblies 24, 26 in one embodiment of the present invention. In the illustrated embodiment, the control valve assemblies 24, 26 include a valve opening or hole 42, a first pressure channel 44, a second pressure channel 46, a valve body land 50, It has the valve body 40 provided with. The valve member 52 is housed in the valve opening 42 for movement between a closed position (eg, see FIG. 4A) and an open position (eg, see FIG. 4D). In one embodiment, the valve member 52 has a valve spool with known magnetic properties, and when the solenoids 28, 30 are energized, they generate a magnetic flux that provides a magnetic force to the valve spool.

図２に示すように、弁部材５２は、第１の弁部材ランド部５４と第２の弁部材ランド部５６とを備えていてよい。図４Ａ〜４Ｄに詳細に示すように、第１の弁部材ランド部５４と弁本体ランド部５０は、協働して、第１の圧力流路４４と第２の圧力流路４６との間に第１の調量流路６０を形成しており、弁本体ランド部５０と第２の弁部材ランド部５６は、協働して、第１の圧力流路４４と第２の圧力流路４６の間に第２の調量流路６２を形成している。このような構成において、弁部材５２は、弁本体４０と協働して第１の圧力流路４４と第２の圧力流路４６との間に流路（ＦＰ）を形成する環状の空洞６４を備えていてもよい（例えば、図３参照）。流路（ＦＰ）は、入口６６と出口６８とを備えている。入口６６及び出口６８は、それぞれ第１、第２の調量流路６０，６２（図４Ｂ，４Ｃ）を形成するのに役立つ。   As shown in FIG. 2, the valve member 52 may include a first valve member land portion 54 and a second valve member land portion 56. As shown in detail in FIGS. 4A to 4D, the first valve member land portion 54 and the valve body land portion 50 cooperate with each other between the first pressure channel 44 and the second pressure channel 46. The first metering flow path 60 is formed in the valve body land portion 50 and the second valve member land portion 56 in cooperation with each other, and the first pressure flow path 44 and the second pressure flow path A second metering flow path 62 is formed between 46. In such a configuration, the valve member 52 cooperates with the valve body 40 to form an annular cavity 64 that forms a flow path (FP) between the first pressure flow path 44 and the second pressure flow path 46. (For example, refer to FIG. 3). The flow path (FP) includes an inlet 66 and an outlet 68. The inlet 66 and outlet 68 serve to form the first and second metering channels 60 and 62 (FIGS. 4B and 4C), respectively.

図２に示されている実施形態では、弁本体４０は、第２の弁本体ランド部７０と、第３の圧力流路７２と、を備えていてもよく、また、弁部材５２は、第３の弁部材ランド部７４をさらに備えていてもよい。第２の弁部材ランド部５６と第２の弁本体ランド部７０は、協働して、第１の圧力流路４４と第３の圧力流路７２との間に第３の調量流路７６（図４Ｂ，４Ｃ）を形成し、第２の弁本体ランド部７０と第３の弁部材ランド部７４は、協働して、第１の圧力流路４４と第３の圧力流路７２との間に第４の調量流路７８を形成する。このような構成において、弁部材５２は、弁本体４０と協働して第１の圧力流路４４と第３の圧力流路７２との間に第２の流路を形成するために第２の環状の空洞８０（図４Ｂ，４Ｃ）を備えていてもよい。   In the embodiment shown in FIG. 2, the valve body 40 may include a second valve body land portion 70 and a third pressure channel 72, and the valve member 52 Three valve member land portions 74 may be further provided. The second valve member land portion 56 and the second valve main body land portion 70 cooperate to provide a third metering flow path between the first pressure flow path 44 and the third pressure flow path 72. 76 (FIGS. 4B and 4C), and the second valve body land portion 70 and the third valve member land portion 74 cooperate to form the first pressure channel 44 and the third pressure channel 72. A fourth metering flow path 78 is formed between the two. In such a configuration, the valve member 52 cooperates with the valve body 40 to form a second flow path between the first pressure flow path 44 and the third pressure flow path 72. The annular cavity 80 (FIGS. 4B and 4C) may be provided.

図３は、弁部材５２が弁本体４０に対して動いたときに、制御弁組立体２４，２６内で流体力がどのようにして生じるかを示している。図示された実施形態では、流体が弁組立体を循環しているとき、流体の流れは、弁部材５２の軸（Ａ−Ａ）に対してほぼ垂直な流路からその軸とほぼ平行な流路へとその方向を変化させ、その後弁部材の軸に対してほぼ垂直な流路に戻る。この流体の流れが、空洞６４の端壁の各々８２，８４に、弁部材の軸とほぼ平行な向きの流体力を与える。図３において、仮に寸法「Ｘ」が寸法「Ｙ」よりも大きいならば、入口６６における流速は、出口６８における流速よりも大きくなるであろう。ベルヌーイ効果により、出口６８に隣接する端壁８２に作用する流体圧は、入口６６に隣接する他の端壁８４に作用する圧力よりも大きい。これによって、図３の矢印で示された方向の、弁部材５２に作用する正味の流体力（Ｆ）が生じる。   FIG. 3 illustrates how fluid forces are generated within the control valve assemblies 24, 26 as the valve member 52 moves relative to the valve body 40. In the illustrated embodiment, when fluid is circulating through the valve assembly, the fluid flow is from a flow path substantially perpendicular to the axis (A-A) of the valve member 52 to a flow substantially parallel to that axis. The direction is changed to a path and then returned to the flow path substantially perpendicular to the axis of the valve member. This fluid flow imparts a fluid force on each of the end walls 82, 84 of the cavity 64 in a direction generally parallel to the axis of the valve member. In FIG. 3, if dimension “X” is greater than dimension “Y”, the flow rate at inlet 66 will be greater than the flow rate at outlet 68. Due to the Bernoulli effect, the fluid pressure acting on the end wall 82 adjacent to the outlet 68 is greater than the pressure acting on the other end wall 84 adjacent to the inlet 66. This produces a net fluid force (F) acting on the valve member 52 in the direction indicated by the arrow in FIG.

図４Ａ〜４Ｄに、様々な作動段階における弁部材５２の位置が示されている。図５に、流体の流れによって弁部材に加えられる流体力（Ｆ）と弁部材の変位量（φ）との関係が、グラフで描かれている。図４Ａ〜４Ｄにおける様々な位置における弁部材５２の変位量は、図番として図５に記載されている。   4A-4D show the position of the valve member 52 at various stages of operation. FIG. 5 is a graph showing the relationship between the fluid force (F) applied to the valve member by the flow of the fluid and the displacement amount (φ) of the valve member. The displacement amounts of the valve member 52 at various positions in FIGS. 4A to 4D are shown in FIG.

図４Ａでは、弁部材５２は、第１の圧力流路４４と第２または第３の圧力流路４６，７２との間に流体が流れない閉位置にある。そのため、図５に示すように、弁部材５２に作用する流体力はほとんど、あるいは全くない。   In FIG. 4A, the valve member 52 is in a closed position where no fluid flows between the first pressure channel 44 and the second or third pressure channel 46, 72. Therefore, as shown in FIG. 5, there is little or no fluid force acting on the valve member 52.

ソレノイドアクチュエータ２８が励起されると、弁部材５２は開位置の方へ移動する。これは図４Ｂに示されている初期移動である。図４Ｂにおいて、他の寸法は全て等しいが寸法「Ｘ1」が寸法「Ｙ1」よりも大きいため、第１の調量流路６０は第２の調量流路６２よりも面積が大きくなる。図４Ｂにおいて、他の寸法は全て等しいが寸法「Ｘ2」が寸法「Ｙ2」よりも小さいため、第３の調量流路７６は第４の調量流路７８よりも面積が大きくなる。従って、各空洞６４，８０で弁部材５２に加えられる流体力（Ｆ）は、ソレノイド２８によって加えられる弁部材５２を移動させる力に抵抗する。図５に示すように、正味の流体力（Ｆ）は、図４Ｂに示す変位量に対応する最大の力に達するまで、流路が開くに従い、増加する。 When the solenoid actuator 28 is energized, the valve member 52 moves toward the open position. This is the initial movement shown in FIG. 4B. In FIG. 4B, all other dimensions are equal, but the dimension “X 1 ” is larger than the dimension “Y 1 ”, so the first metering channel 60 has a larger area than the second metering channel 62. . In FIG. 4B, since all other dimensions are equal, but the dimension “X 2 ” is smaller than the dimension “Y 2 ”, the third metering channel 76 has a larger area than the fourth metering channel 78. . Accordingly, the fluid force (F) applied to the valve member 52 in each cavity 64, 80 resists the force that moves the valve member 52 applied by the solenoid 28. As shown in FIG. 5, the net fluid force (F) increases as the flow path opens until reaching the maximum force corresponding to the displacement shown in FIG. 4B.

図４Ｃに示すように弁部材５２がさらに開位置の方へ移動すると、寸法「Ｘ1」と寸法「Ｙ1」とがほぼ等しくなり、かつ寸法「Ｘ2」と寸法「Ｙ2」とがほぼ等しくなるまで、ソレノイドの力に抵抗する正味の流体力（Ｆ）は減少する。この位置では、ソレノイドの力に抵抗する流体力がなくなる（図５の位置４Ｃを参照）。 As shown in FIG. 4C, when the valve member 52 moves further toward the open position, the dimension “X 1 ” and the dimension “Y 1 ” become substantially equal, and the dimension “X 2 ” and the dimension “Y 2 ” Until approximately equal, the net fluid force (F) resisting the solenoid force decreases. In this position, there is no fluid force that resists the force of the solenoid (see position 4C in FIG. 5).

弁部材５２が、図４Ｄに示すようにさらに開位置の方へ移動すると、他の寸法は全て等しいが寸法「Ｘ1」は寸法「Ｙ1」よりも小さくなるため、第２の調量流路６２は第１の調量流路６０よりも面積が大きくなる。図４Ｄにおいて、他の寸法は全て等しいが寸法「Ｘ2」は寸法「Ｙ2」よりも大きくなるため、第４の調量流路７８は第３の調量流路７６よりも面積が大きくなる。従って、各空洞６４，８０で弁部材５２に加えられる流体力（Ｆ）は、ソレノイド２８によって加えられる弁部材５２を移動させる力を補助する。図４Ｄに示されている開位置では、正味の流体力（Ｆ）は、弁部材を開位置に保持するように作用し、弁部材が開位置から実質的に移動することなくソレノイド２８を非作動状態とすることができる。 When the valve member 52 is further moved toward the open position as shown in FIG. 4D, all the other dimensions are equal, but the dimension “X 1 ” is smaller than the dimension “Y 1 ”, so the second metering flow The area of the channel 62 is larger than that of the first metering channel 60. In FIG. 4D, all the other dimensions are equal, but the dimension “X 2 ” is larger than the dimension “Y 2 ”, so the fourth metering channel 78 has a larger area than the third metering channel 76. Become. Accordingly, the fluid force (F) applied to the valve member 52 in each cavity 64, 80 assists in the force that moves the valve member 52 applied by the solenoid 28. In the open position shown in FIG. 4D, the net fluid force (F) acts to hold the valve member in the open position, deactivating solenoid 28 without substantially moving the valve member from the open position. It can be in an operating state.
