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： 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： A system for storing and dispensing a liquid cleaning additive for a high-pressure cleaning appliance has a device for storing the cleaning additive and a device for dispensing the cleaning additive in a controlled manner. In order to develop the system such that it is easier to handle, it is proposed that the storage device has an intermediate tank, which is fixedly held on the high-pressure cleaning appliance, and an independently handlable refill container for filling the intermediate tank, it being possible for liquid cleaning additive to be withdrawn in a controlled manner from said intermediate tank by means of the dispensing device, it being possible for the refill container to be secured on the high-pressure cleaning appliance and to be flow-connected to the intermediate tank, cleaning additive flowing automatically out of the refill container into the intermediate tank upon withdrawal of cleaning additive from the intermediate tank, in order to maintain a predetermined liquid level in the intermediate tank. A refill container for such a system and also a high-pressure cleaning appliance having such a system are also proposed.

摘要： In a closure device for the fluid delivery line of a high-pressure cleaning apparatus having arranged in the fluid delivery line a closure member which is pressed with a closing force against a valve seat and thereby closes the fluid delivery line, and which is liftable off the valve seat by a mechanical actuating element displaceable by a hand lever and extending in a sealed manner out of the fluid delivery line, when the hand lever is moved in the direction of an open position, in order to reduce the holding forces when the hand spray gun is open, it is proposed that downstream of the valve seat in the fluid delivery line a displaceably mounted piston extend in a sealed manner out of the fluid delivery line and upon being pushed out of the fluid delivery line cooperate with the hand lever in such a manner that the hand lever is moved in the direction towards its open position.
