Fluid pressure actuated switch for fluid pump |
摘要 |
A pressure switch for operating a device for increasing the engine speed of an automotive vehicle equipped with a power steering system in order to prevent an engine stall when a high load acts on a power steering pump during parking and at a low vehicle cruising speed. The pressure switch is comprised of a movable terminal which is normally separate from a stationary terminal and contactable with the stationary terminal in response to an oil pressure over a predetermined level, in a hydraulic circuit of the power steering system. The movable terminal is slidably fitted in a pit to be filled with oil so that the response of the movable terminal to the oil pressure is lowered, thus providing a hysteresis effect to prevent chattering of the pressure switch.
