Abstract

PURPOSE:To eliminate a time lag from jetting to wiping by providing a control valve which selectively communicate with only the jetting nozzle which opens facing the face to be wiped prior to the movement of each wiper in both swing directions of wipers. CONSTITUTION:When a wiper reaches both wiper switching dead points, swinging speed of the wiper becomes zero once, and then, speed direction is reversed. A sliding piece 4 receives the acceleration produced at this moment, and when the wiper swings to the left, the sliding piece 4 moves to the right by rolling in a distribution chamber 6. When the wiper finishes the movement to either end, the sliding piece 4 a valve seat 7 contact with each other closely. Therefore, if the wiper is in the middle of moving to the left, the sliding piece 4 is in the right side, contacts with the right valve seat 7 closely, to close the communication to the right jetting port, and opens only the left jetting port to jet washer liquid. In this case washer liquid is jetted only from the left jetting port, resulting in the jetting of washer liquid only to the face to be wiped prior to wiper motion.

With the above-described structure, when both dead points of the swing of the wiper are reached, the swing speed once becomes 0, and then the speed direction is reversed. When the wiper moves to the left, the slider 4 rolls in the distribution chamber 6 to the right when the wiper moves to the left. The opposite is true when the wiper moves to the right. When the movement to any one of the ends is completed, the slider 4 and the valve seat 7 come into close contact with each other.

Therefore, if the wiper is in the process of moving to the left, the slider 4 is located to the right and is in close contact with the valve seat 7 on the right to block conduction to the jet port on the right. However, only the left ejection port is electrically connected and ejected. This is just in the process of moving in the direction of the arrow in FIG. 1, and since the washer liquid is sprayed only from the jet outlet on the left side, it must be sprayed only on the wiping surface (FIG. 1A) preceding the movement of the wiper. Becomes

Due to the swing angle condition of the wiper, the slider may be located above the distribution chamber during the moving process. In this case, the slider 4 should normally fall during the process and separate from the valve seat 7. However, as shown in the schematic diagram of FIG. 4, the area of the valve seat inner diameter d is A, and the weight of the slider 4 is self-weight. Is W and the supply pressure of the washer fluid is p, the inner diameter d is set so that pA> W, so that the slider 4 does not separate from the valve seat 7 during the process. In addition, when there is a small amount of leakage at the valve seat contact portion, the washer liquid flows and receives dynamic pressure in the area of the diameter D of the slider 4 and is pressed against the valve seat 7 again and becomes stable.

Next, the second embodiment shown in FIG. 5 will be described. In this case as well, the same reference numerals are given to the parts having the same functions as those in the first embodiment. The second embodiment uses a cylindrical body as the slider 4 instead of a steel ball. Both ends of the cylindrical body are tapered to measure the close contact with the valve seat 7, and the point that the slider 4 and the valve seat 7 constitute the control valve is the same as in the first embodiment. , There is no change in the action. The feature of the second embodiment is that the degree of freedom in setting the weight of the slider 4 is greater than that of steel balls. The slider 4 does not roll in the distribution chamber 6 but moves by sliding.

Next, a third embodiment shown in FIG. 6 will be described. In this example as well, the same reference numerals are given to the parts that have the same functions as in the first embodiment. In this example, the free piston 15 instead of the slider 4 moves in the distribution chamber 6. Further, instead of lacking the valve seat 7, the fitting of the free piston 15 and the distribution chamber 6 is finished finely with as much space as possible within a range where it slides without resistance. The moving action of the free piston 15 in this case is the same as in the previous example, but the pressure from the washer pump is received by the entire piston diameter.

According to the present invention, since the washer fluid can be selectively jetted only from the jet port which is opened toward the wiping surface preceding the movement of the wiper, it is necessary to make a fine adjustment of the jet direction of the washer fluid. The optimum range can be reached accurately. Therefore, the amount reached is too small, stroking the muddy water of the window to warp the field of view, and it may take some time from the arrival of the washer liquid to the wiping at high speeds, and it may be sprayed on the already wiped surface. Thus, it can contribute to safe driving without obstructing the view.
