Abstract
A washer solution hose controlling device includes a car speed sensor and an electronic control device outputting a control signal in proportion to the car speed detected from the car speed sensor. The washer solution hose controlling device further employs a solenoid where the voltage supplied from the battery, depending upon the control signal output of the electronic control device which is in proportion to the car speed, is varied. Both sides of a feed hose are pushed by the solenoid to increase the injection pressure of washer solution proportionate to the detected car speed.
Claims6
A washer system comprising:
- a tank filled with a first fluid;
- a hose having a cross-sectional area, said hose being connected to said tank;
- a nozzle connected to said hose;
- a pump operatively linked to said hose and said tank, said pump moving the first fluid through said hose and said nozzle;
- a switch;
- means for reducing said cross-sectional area of said hose;
- a sensor generating a value based on translational movement of the washer system relative to a terrain;
- and
- an electronic control unit operatively linked to said switch, said pump, said reducing means, and said sensor;
- upon activation of said switch, said electronic control unit provides a control signal to said reducing means which is proportional to said value of said sensor, whereby said reducing means changes said cross-sectional area of said hose and the first fluid ejected from and outside said nozzle maintains a predetermined direction irrespective of contact with a second fluid disposed outside said nozzle.
