    • An upright electric cleaning device includes a floor suction tool formed with a long suction opening on the bottom surface thereof. A rotating brush holding chamber holds a rotating brush that extends to this long suction opening. A suction opening leading to the main cleaning device unit is formed toward one end of the rear wall of the rotating brush holding chamber. A rib, formed on the upper section of the rotating brush holding chamber, extends along the length of the rotating brush, near the rotation path of the rotating brush. An air current path is formed to take dust drawn up by the rotating brush and stopped by the rib and suck it into the suction opening leading to the main cleaning device unit. The air current path is shaped so that its cross section is smaller at an end of the air current path remote from the suction opening than it is near the suction opening to increase flow speed at the remote end. In one embodiment, an opening to the outside is formed at the remote end of the air current path to enhance air flow toward the suction opening. In a further embodiment, the enhanced air flow if further improved by venting exhaust air from the main cleaning device into the opening to positively improve air flow.
    • 立式电动清洁装置包括在其底表面上形成有长吸入口的地板吸入工具。 旋转刷保持室保持延伸到该长吸入口的旋转刷。 通向主清洁装置单元的吸入口朝向旋转刷保持室的后壁的一端形成。 形成在旋转刷保持室的上部的肋沿着旋转刷的长度在旋转刷的旋转路径附近延伸。 形成气流路径,以吸收由旋转刷牵引并由肋停止的灰尘并将其吸入通向主清洁装置单元的吸入口。 气流路径的形状使得其远离吸入口的气流路径的端部处的截面小于其在吸入口附近的横截面,以增加远端的流速。 在一个实施例中,在气流路径的远端处形成有一个到外部的开口,以增强朝向吸入口的气流。 在另一个实施例中,如果通过将排气从主清洁装置排放到开口中而进一步改善,则增强的空气流积极地改善空气流。

    • A hydraulic device includes a switch-over valve 1140 provided at a section of a sub-passage 1105 located downstream of a location where a first bypass passage 1117 is connected and located upstream of a primary regulator 1110. The switch-over valve 1140 is switched between a blocked state, where supply of hydraulic oil to a section of the sub-passage 1105 located downstream of the switch-over valve 1140 is blocked, and a communication state, where supply of hydraulic oil to the section of the sub-passage 1105 located downstream of the switch-over valve 1140 is permitted. In the hydraulic device, when the switch-over valve 1140 is switched to the communication state, as a discharge performance of a main pump 1102 increases, a first check valve 1118 closes. Supply paths for hydraulic oil discharged from the sub-pump 1103 are automatically switched in accordance with the discharge performance of the main pump 1102. When the switch-over valve 1140 is switched to the blocked state, the first check valve 1118 opens and hydraulic oil discharged from the sub-pump 1103 is introduced into a main passage 1104.
    • 液压装置包括设置在位于第一旁通通道1117连接并位于主调节器1110的上游的位置下游的子通道1105的部分处的切换阀1140.切换阀1140被切换 在向位于切换阀1140下游的子通道1105的一部分供应液压油的堵塞状态之间,以及连通状态,其中向子通道1105的部分供应液压油 位于切换阀1140的下游。 在液压装置中,当切换阀1140切换到通信状态时,随着主泵1102的排出性能的增加,第一止回阀1118关闭。 从副泵1103排出的液压油的供给路径根据主泵1102的排出性能自动切换。当切换阀1140切换到阻塞状态时,第一止回阀1118打开,液压油 从副泵1103排出的空气被引入主通路1104。
