Claims

[Scope of utility model registration request]

(1) Oil level detection is activated when the oil level in the oil tank of the power unit that supplies pressure oil to the hydraulic jack for raising and lowering the car drops to a predetermined oil level set above the oil outlet. In the oil level detection device for a hydraulic elevator, the oil level detection position of the oil level detector is set from a position lower than the oil level level in the tank when the car is raised to the top floor stop position. An oil level detection device for a hydraulic elevator, characterized in that the oil level is set between the level of the oil level in the tank when the car is raised past the top floor stop position until the plunger of the hydraulic jack reaches its lifting limit.

(2) The oil pressure detector is a float-type detector consisting of a guide with a built-in switch inserted into the oil tank and a float with a built-in magnet that moves up and down along this guide as the oil level moves up and down. An oil amount detection device for a hydraulic elevator as set forth in claim (1) of the registered utility model.

(3) The hydraulic elevator according to claim 1 or 2, wherein the oil level detector is provided on the opposite side of the oil tank from the recirculated oil inlet. Oil level detection device.

(4) Any one of claims (1) to (3) for utility model registration, characterized in that the oil level detector is provided in a space divided by a wave-proof partition plate. The oil amount detection device for a hydraulic elevator described in .
