Description
The present invention relates to employed pressure regulator valve in a kind of oil pressure control at various oil pressure devices.
Be provided with a plurality of mating members in the vehicle automatic transmission, by cooperating 1 of these elements or several selectively, and obtain a plurality of grades of speed changes, as the pressure regulator valve of the oil pressure of control mating member, known valve as shown in Figure 1.
This pressure regulator valve has valve body 1 and axially can move freely in valve body 1 and the guiding valve 10 established.Valve body 1 is made up of input hole 2, tap hole 3, delivery outlet 4, feedback hole 5, telltale hole 7.Delivery outlet 4 is located at the middle part between input hole 2 and the tap hole 3, feedback hole 5 is located at the end of input hole 2 sides, telltale hole 7 is located at the other end relative with feedback hole 5, it is the end of tap hole 3 sides, guiding valve 10 is valve rods that input hole 2 and delivery outlet 4 or tap hole 3 and delivery outlet 4 are communicated with selectively, for delivery outlet 4 and feedback hole 5, make it be configured to connecting shape by the intercommunicating pore 11 that on guiding valve 10, processes.Intercommunicating pore 11 be by the axle center hole 11a of the feedback hole side that is communicated with guiding valve 10 and from over against the position of delivery outlet 4 to axle center hole 11a, the via hole 11b that processes at radial direction is constituted.When feedback hole 5 feedback outputs are pressed,, can prevent to export the pulsation of pressure owing to be provided with via hole 11 at intercommunicating pore 11.At input hole 2, for example import line pressure, delivery outlet 4 is connected with mating member, at feedback hole 5 places guiding valve 10 is equipped with the spring 6 that is pressed into to a direction, for example has signal pressure to be transfused to from solenoid valve at telltale hole 7.
When input signal was pressed at telltale hole 7 places, guiding valve 10 was by spring 6 effects and locate left position, and delivery outlet 4 is communicated with tap hole 3, from delivery outlet 4 output oil pressure not.
On the other hand, when telltale hole 7 place's input signals are pressed, guiding valve 10 top springs 6 and moving to right, when tap hole 3 is closed, will be communicated with delivery outlet 4 and input hole 2, thus, in the time of from delivery outlet 4 output oil pressures, by intercommunicating pore 11, the output pressure is fed at feedback hole 5 places, and the output that guiding valve 10 is fed back by the elastic force and feedback hole 5 places of spring 6 is pressed sum to return to left and pushed away.
As mentioned above, guiding valve 10 is pushed away by the signal extrusion that comes from left, by pushing away from the elastic force of right-hand spring 6 and the squeezing with joint efforts of output pressure of feedback hole 5 feedbacks, thus, 10 pairs of delivery outlet 4 limits of guiding valve selectively are communicated with input hole 2 or tap hole 3, the limit averages out, and the fixed oil pressure adjustment of professional etiquette is compressed in output.
Yet when importing high signal pressure once at telltale hole 7 places, guiding valve 10 is pushed the position of giving as security right-hand member always.At this moment, the sidewall of feedback 5 is run in the right side of guiding valve 10, and axle center hole 11a becomes closed shape.When this state, by intercommunicating pore 11, both made feedback hole 5 desires feedback had been pressed in output, the compression area of guiding valve 10 only can guarantee to venerate greatly the area of axle center hole 11a internal diameter size, guiding valve 10 to left pushing force deficiency, is obtained as shown in Figure 1 the result that the involution to the equilibrium position postpones.
In order to eliminate this inappropriate situation, be processed into otch ditch 11c in the right side of guiding valve 10, when the sidewall of feedback hole 5 is run in the right side of guiding valve 10, axle center hole 11a can not seal, therefore, the compression area of guiding valve 10 can guarantee that involution promptly is to balance position shown in Figure 1.
Yet, the right side of above-mentioned guiding valve 10 will process otch ditch 11c, need machining period, the shortcoming that has cost to uprise, that is, and during processing guiding valve 10, generally be that the garden bar material is processed axle center hole 11a, car goes out outer shape, after the via hole 11b of processing radial direction, mills out otch ditch 11c at end face again.
When making such guiding valve 10, need three different process segments at least, the shortcoming that machining period is many, bring cost to rise is arranged, particularly, in order to mill out otch ditch 11c, to unload guiding valve again from the perforation processing machine and be installed, thereby constitute the reason that increase man-hour.
Therefore, the purpose of this invention is to provide one and need not be the work of milling that need, and the minimizing machining period, can reduce the pressure regulator valve of manufacture cost at the end face of guiding valve processing otch ditch.
For achieving the above object, the invention provides a kind of pressure regulator valve: have the formation input hole, tap hole, the valve body of delivery outlet and feedback hole and in valve body, axially be provided with, can move freely the guiding valve that delivery outlet is communicated with selectively input hole or tap hole, make between delivery outlet and the feedback hole and be communicated with by the intercommunicating pore that on guiding valve, forms, it is characterized in that, above-mentioned intercommunicating pore, have the axle center hole that is communicated with feedback hole that on the axle center of guiding valve, processes and the via hole of the oil pressure of delivery outlet being supplied with axle center hole is arranged, the end face of above-mentioned feedback hole towards guiding valve processes minor diameter part, between the outer circumferential face and axle center hole of this minor diameter part, process and the hole of above-mentioned via hole with the footpath.
In the present invention, end in the feedback hole side of guiding valve, be provided with the minor diameter part littler than the inner circle wall of feedback hole, process and the hole of via hole at this minor diameter part with the footpath, thus, when guiding valve is run into the sidewall of feedback hole side, attract oil pressure from axle center hole to the outside of minor diameter part, can obtain with in the past process the same function of otch ditch at the guiding valve end face.And, can use process with the same instrument of via hole and via hole with the hole in footpath, thereby defeasible processing otch ditch mill work, reduced man-hour.
When the milling oral groove, because the end remainder sectional area of guiding valve diminishes, guiding valve was through repeatedly bumping the wall of feedback hole, the end face abrasion or the distortion of guiding valve in the past.In addition, the end face of guiding valve deforms when alive milling, and might make the stop position of guiding valve produce deviation, and to this, the present invention does not process the end face of guiding valve, and when the abrasion of end face can reduce, the end face of guiding valve did not deform yet.
In addition, in above-mentioned pressure regulator valve, minor diameter part processing with the hole of via hole with the footpath, also passable with the equidirectional processing of via hole, that is, with punching machine after having processed via hole, do not need guiding valve is turned to, guiding valve is axially moved, get final product from the equidirectional machining hole of going up, thereby can punch expeditiously.
