Abstract

DC60 oil level detector kit with float type oil level detector (50) and mode switching unit. The oil level detector emits a signal indicating that the Engine oil Decreased when the movable contact provided on the float (54) came into contact with the Fixed touch when the oil level (Lu) has dropped to the lower limit level, the mode switching unit switches between one of the two selected modes. It is from the first mode to trigger the alarm to start and stop the engine (10) following the lowering signal and the second mode to trigger the alarm to start the engine (10) following the reduction signal. Such level Oil level detector kit with float type oil level detector (50) and mode switching unit. The oil level detector emits a signal indicating that the Engine oil Decreased when the movable contact provided on the float (54) came into contact with the Fixed touch when the aforementioned Lu (Lu) level has dropped to the lower limit, which mode switching unit will switch between? Mode one of the two modes selected from one to trigger. Alarms to start and stop the engine (10) following the lowering and The second mode to stimulate The alarm is triggered to enable the engine (10) to follow the lowering signal.

Claims (3)

Disclaimers (all) that will not appear on the advertisement page: 1. In engines for operating machines of this type consisting of an oil dipstick which It is provided in the engine crankcase for higher oil pressure with crankshaft rotation and supplying oil to various sliding parts. And a set of equipment to detect oil level, float type Which is placed in the crankcase for detecting the engine oil level By the engine oil level detection device Float type includes: - Oil level detector for emitting a signal indicating that the oil level has dropped. Then when the mobile contact provided on the float comes into contact with the stationary contact. Of the engine oil has dropped to a predetermined lower limit, - the mode switching unit for It is based on the type of operating machine, switches between modes one for triggering the alarm following the reduction signal and Causing the engine to stop working And a second mode for triggering the alarm to start Follow the lowering signal and let the engine continue to run, and - First and Second Judging Unit to determine the level of engine oil. It has actually decreased. Its characteristics are: - The first judgment unit judges that the level of the said engine oil has actually decreased. To such a lower limit when both conditions are met, that is, engine conditions It stopped working And the condition that the signal duration shows a complete reduction in accordance with the reference period One that is predetermined and - the second judgment unit determines that the level of the said engine oil has actually decreased. To such a lower limit when both conditions are met, that is, engine conditions It is working And the condition in which the number of times a signal is received shows such reduction at the interval that Shorter than the second predefined reference time, increases the number of pre-defined reference times. 2. The engine oil level detector set according to claim 1, which is unique is that the mode switching unit consists of a user-operated switch that can be installed on the operator's panel. Such engine has 3. The engine oil level detector set according to claim 1, which is characterized by a mode switch unit, consists of a memory provided on the engine to store mode switching data and a switching actuator that can switch between modes. One such and a second such mode by adherence to The mode switching information stored in the memory. Where the said memory is configured Design so that the mode switching data can be written according to communication from the external communication unit.
