Title:
DEVICE FOR DRIVING BLOWER OF LAWN MOWER
Document Type and Number:
Japanese Patent JP3424261
Kind Code:
B2
Abstract:
PURPOSE: To prevent the inflow side of a hydraulic fluid from changing into a state of a negative pressure in stopping a hydraulic motor by installing an oil passage equipped with a check valve between the inflow side of the hydraulic fluid for the hydraulic motor for a blower and the discharge side of the hydraulic fluid.
CONSTITUTION: An oil passage 74 equipped with a check valve 72 capable of making a discharged hydraulic fluid flow thereinto is installed between the inflow side of the hydraulic fluid of a hydraulic motor 53 for rotating and driving a blower 55 and the discharge side of the hydraulic fluid thereof. Even when the inflow side of the hydraulic fluid of the hydraulic motor starts changing into a negative pressure, the hydraulic fluid flows from a tank 69 into the side of the hydraulic motor without causing a cavitation phenomenon.
