摘要： A power steering system includes a hydraulic power cylinder, a hydraulic pump for supplying an oil pressure to the hydraulic power cylinder, an electric motor for driving the hydraulic pump, a first detector for detecting a steering assist force to be applied to a steering wheel, a second detector for detecting an operating condition of the electric motor, and a controller. The controller includes a control section for controlling the electric motor based on the required steering assist force detected by the first detector so as to cause the hydraulic pump to produce a required oil pressure, and a determining section for determining based on the operating condition of the electric motor and the required steering assist force detected by the first detector whether or not the power steering system is abnormal.

摘要： A suction inlet unit (30) comprises a suction inlet main body (31) having a bottom suction inlet (32), a front suction inlet (46) formed continuously with said bottom suction inlet (32) in the front of said suction inlet main body (31), and a cover (50) for covering the front suction inlet (46). The cover, provided at the suction inlet main body (31) movable by an adjusting mechanism for adjusting an opening area size of said front suction inlet (46) to a determined area, is configured to decrease the opening area of the front suction inlet (46) when a front portion of the cover 50 is contacted by a wall or furniture.
