Abstract: Electrical machine (12) having a shielding plate (10), wherein the electrical machine (12) comprises a housing part (32) in which is arranged an electronic unit (14), and said electrical machine also comprises a metal heat sink (34) that is arranged on the housing part (32), wherein the electronic unit (14) is arranged between the shielding plate (10) and the heat sink (34).

Abstract: A fan arrangement (1), in particular for cooling an engine system, comprising: an impeller (10) having one or more blades (4) which in operation convey a medium in the direction of an axis of rotation of the impeller (10) from an inlet side (E) to an outlet side (A); a housing shroud (6) having a base part (61) which extends in the direction of the axis of rotation and surrounds the impeller (10) completely or partially, wherein, on an end of the base part (61) oriented towards the outlet side (A) of the impeller (10), there is provided a discharge flow element (63) which extends radially outwards from the end of the base part (61).

Abstract: A fan (20) comprises a fan hub (22), fan blades (24) which are mounted on the fan hub (22), and a drive motor having an outer rotor (30), wherein the outer rotor (30) is arranged inside the fan hub (22). The outer rotor (30) is arranged in the fan hub (22) in such a way that the outer rotor (30) is supported in a radially outward direction on the radial outer wall (36) of the fan hub (22), by means of cooling fins (32) which are formed integrally with the fan hub (22).

Abstract: A haemostatic valve assembly (18) is provided with a housing (24) having first and second ends (26, 28) within each of which there is provided an aperture of opening (30, 32). A flexible valve element (34) is disposed within the housing (24) between the first and second openings (30, 32). A mass of separate pellets (40) is located within the chamber (38) formed between the housing (24) and the valve element (34). The pellets (40) apply pressure to the valve element (34) so as to close the lumen (36) thereof. The pellets (40) are preferably made of a compressible material and such that when an element is inserted through the openings (30, 32) and thus through the valve assembly (18) the pellets (40) compress to allow opening of the lumen (36). The biasing force of the pellets (40) against the valve (34) provide constant sealing pressure to the valve assembly (18) without the need for any intervention by the clinician. The valve assembly is therefore entirely automatic.

Abstract: A fan includes a hub and blades. A first edge of each blade is proximate an open end of the hub. A first rib is coupled to the hub and substantially aligned with a first plane intersecting the central axis and an intersection of the first edge of the first blade with the hub. The first plane is angularly spaced from a reference plane intersecting the central axis and an intersection of the first edge of the second blade with the hub. An angular spacing between the first plane and the reference plane defines one sector. A second rib is aligned with a second plane angularly positioned between the first plane and the reference plane at a location less than or equal to about (1/nR?0.05) sectors from the first plane, in which nR equals the number of ribs divided by the number of blades.

Abstract: A water supplying device of a hand-held power tool has a water-conveying line and a valve arrangement arranged in the line for controlling the water flow through the line. The valve arrangement has a control valve with a valve body adjustable across a positioning travel. The opening cross-section of the control valve, as a function of the positioning travel, has a progressive characteristic line. An arrangement for actuating the water supplying device has an actuator that is separate from additional control elements of the power tool.

Abstract: A portable spray apparatus (1) is provided to selectively discharge liquid spray medium and solid dust medium with a blower airflow (7) generated by a blower (6). An adaptor (8) is provided which has at least a channel section (9) of a liquids channel (10) for the liquid spray medium and a channel section (11) of a solids channel (12) for the solid dust medium. The adaptor (8) is releasably connected to a supply vessel (4). The liquids channel (10) and the solids channel (12) open into the blower airflow (7). Various built-in positions of the supply vessel (4) and of the adaptor (8) are freely selectable relative to each other and to the blower unit (3) by the operator. In one built-in position, the liquids channel (10) is connected via its channel section (9) to an interior space (13) of the supply vessel (4) and, in another built-in position, the solids channel (12) is connected to this interior space (13) via the channel section (11) thereof.
