Embodiment
As from herein understand, below discuss will relate to a kind of oil control valve, this oil control valve is configured for cylinder deactivation valve (cylinder deactivation valve).But configuration disclosed is in this article applicable to other valves being configured to use together with poppet valve core.
First with reference to figure 1, illustrate and indicate the oil control valve constructed according to the present invention with reference character 10.Oil control valve 10 can comprise governor assembly 20, valve body 30, core 36 and armature 38 usually.Valve rod 40 can comprise threaded end 42 far away.Poppet valve core 44 threadably can be connected to the threaded end far away 42 of valve rod 40.Valve body 30 can have valve seat 48.When supplying energy (powering up) to core 36, valve rod 40 can along direction translation to the right as shown in Figure 1 until poppet valve core 44 engages with valve seat 48.When poppet valve core 44 engages with valve seat 48, stop the flowing of oil between poppet valve core 44 and valve seat 48.
Governor assembly 20 can comprise regulator body 60, and this conciliation body receives check valve assembly 64.Check valve assembly 64 can comprise check ball 70 and biasing member 72.Regulator body 60 can be limited with and regulate mouth 76.Regulator body 60 also can comprise poppet valve core stop configurations 80.This poppet valve core stop configurations 80 can comprise a series of poppet valve core stop member 82 radially arranged around regulator body 60.In a configuration, poppet valve core stop member 82 can form with regulator body 60.Regulation valve body 60 can be made up of cast Zn-Al alloy or other materials.As from herein understand, poppet valve core stop member 82 is arranged so that, when poppet valve core 44 separates with valve rod 40, poppet valve core 44 can only lean against on the poppet valve core stop member 82 of the poppet valve core stop configurations 80 on regulator body 60.In this regard, do not allow poppet valve core 44 to enter to regulate in mouth 76 and block the flowing of oil.In addition, poppet valve core stop member 82 is located so that poppet valve core stop member 82 can not contact with poppet valve core 44 and not affect normal function when poppet valve core 44 is suitably attached to valve rod 40.
Fig. 2 illustrates a configuration, and wherein poppet valve core stop configurations 80 comprises three poppet valve core stop members 82.Poppet valve core stop member 82 is arranged to radially 120 degree, interval.Adjacent poppet valve core stop member 82 is limited with annular space 100 between which.Annular space 100 be arranged to such as when poppet valve core 44 separates with valve rod 40 (hereinafter further illustrating) for the flowing of oil.Also other configurations can be imagined.In example shown in fig. 2, each poppet valve core stop member 82 is connected with the interior cylindrical side wall 110 of regulator body 60 and extends from cylindrical side wall 110 in regulator body 60.Each poppet valve core stop member 82 extends to the transverse wall 114 of regulator body 60 from interior cylindrical side wall 110.Transverse wall 114 substantially transversely extends relative to the axis 116 of regulator body 60.Transverse wall 114 limits porose 118, and the cooperation of this hole is passed through to regulate mouth 76 to make fluid.
Each poppet valve core stop member 82 also can comprise poppet valve core stop member opposed wall portion 120, axial walls part 122 and connecting wall part 124.In one example, axial walls part 122 can concavely roughly to match with the geometrical shape in hole 118.But should be understood that, axial walls part 122 can have other geometrical shapies, such as plane or convex.In one example, axial walls part 122 can limit the diameter D1 (see Fig. 8) larger than the diameter D2 in hole 118.Poppet valve core stop member opposed wall portion can be roughly parallel to transverse wall 114.Connecting wall part 124 can be angled transition wall, and this transition wall has the first curved wall portion 130 at poppet valve core stop member opposed wall portion 120 place and the second curved wall portion 132 at axial walls part 122 place.First and second curved wall portion 130 and 132 can have concave profile substantially, and this concave profile is with mouth 76 and hole 118 is concentric or essentially concentric.
Fig. 3-8 illustrates multiple illustrative configuration of regulator body 60.As above, poppet valve core stop member 82 is arranged so that, when poppet valve core 44 separates with valve rod 40, poppet valve core 44 can only lean against on the poppet valve core stop member 82 of the poppet valve core stop configurations 80 on regulator body 60.Particularly, in holding position, poppet valve core 44 can engage (see Fig. 4) with each poppet valve core stop member opposed wall portion 120.More particularly, poppet valve core 44 comprises poppet valve core head 138, and this poppet valve core head 138 comprises the first end 140 being configured to engage with valve seat 48 (Fig. 1) and the radial lip 142 arranged on opposite ends.The radial lip 142 be arranged on poppet valve core 44 engages with each poppet valve core stop member opposed wall portion 120 and is prevented from marching to further in mouth 76.In holding position, fluid is still allowed to flow through each annular space 100 limited between adjacent stop member 82.See also the stream F shown in Fig. 7.
Now especially with reference to figure 3 to 6, the supplementary features of regulator body 60 will be described.Regulator body comprises central hub portion 144 and flange 146.Circular groove portion 148 is formed between central hub portion 144 and flange 146.Circular groove portion 148 can be configured to receive sealing component, such as O-type seal ring 150 (Fig. 1).
The explanation to previous embodiment is provided for the object illustrated and describe.This is not want exhaustive or restriction the present invention.Independent element in specific embodiment or feature are not limited to this specific embodiment usually, but interchangeable and can be used for (if words applicatory) in the embodiment selected, even if do not specifically illustrate or describe.Described element or feature also can change in the mode that many kinds are different.These changes are not considered as departing from the present invention, and these all changes are all contained within the scope of the invention.
