摘要： A centrifugal fan with a pot-like impeller and with a housing, having a first circumferential wall region with an arc-like curvature which extends directly along the impeller. The housing includes in a direction of rotation of the impeller a second circumferential region with a radial distance from the impeller increasing spirally up to an outlet region. The housing includes in an opposite direction a third circumferential wall region extending to the outlet region, having an S-curvature and including a sub-region curved in the same direction as the first circumferential wall region forming a flow baffle element. Two side walls cover the axial end faces of the impeller wherein one of the side walls extends into the pot-like impeller and divides its interior into a first suction chamber having an intake and a second suction chamber. The outlet region expands in cross-section in the outlet flow direction.

摘要： Proposed is a centrifugal fan with a pot-like impeller (10) and with a housing (11) accommodating the impeller (10), the circumferential wall (18) of which, starting from a first circumferential wall region (19) with an arc-like curvature which extends directly along the impeller (10), comprises on the one hand in the direction of rotation of the impeller (10) a second circumferential region (20) with a radial distance from the impeller (10) increasing spirally up to an outlet region (21) and on the other hand against the direction of rotation of the impeller (10) a third circumferential wall region (22) likewise extending to the outlet region (21). Two side walls (25, 26) cover the axial end faces of the impeller (10), wherein a partition (28) on one of the side walls extends into the pot-shaped impeller (10) and divides its interior into a first (V1) and a second (V2) suction chamber, an intake (29) being assigned to the first suction chamber (V1). The third circumferential region (22), starting from the first circumferential region (19), has an S-curvature towards the outlet region (21), its sub-region (24) curved in the same direction as the first circumferential wall region (19) forming a flow baffle element for the air flow returned to the second suction chamber (V2). The outlet region (21) expands in cross-section in the manner of a diffuser in the outlet flow direction. This design results in a centrifugal fan with increased efficiency and increased fan power combined with a lower volume.

摘要： The invention relates to a high-pressure cleaning device having a housing in which a pump and a drive motor are disposed, it being possible for pressurized liquid to be delivered by the pump via a high-pressure hose and it being possible for the high-pressure hose to be wound onto a hose drum which is mounted within the housing such that it can rotate about a rotation axis, and for said high-pressure hose to be routed out of the housing at the rear. In order to develop the high-pressure cleaning device in such a way that it has a shorter structure, the invention proposes aligning the rotation axis of the hose drum parallel to the horizontal axis of the housing.

摘要： The subframe contains a framework which is cast as a single part and has profiled hollow members for the longitudinal and cross members. The cross members are connected to each other via supporting pillars at the corners, or are integrally formed on the supporting pillars. Arms which protrude outward are integrally formed on the supporting pillars or on the longitudinal and cross members, the end sides of which arms have connecting bearings toward the vehicle body. A differential is held on the two cross members, the differential having one mounting on the front cross member and two mountings on the rear cross member. The longitudinal members have a curved passage opening for the drive shafts of the differential. Mountings for wheel guiding links are arranged on the outside of the longitudinal member.
