Through the shower head, grading regulation is realized in flow control; and the two buttons are used for controlling increase and reduction of the flow respectively, so that the shower head is definite and easy to operate. Under the control of the buttons, the internal regulating structure is tangential with the water flow direction, so the regulating force is small.

The invention relates to a gas feed method for a gas engine or dual-fuel engine in which combustion gas (G) is burned with combustion air (L), wherein a gas valve (1) for the feed of combustion gas (G) into the combustion air (L) is arranged upstream of the gas engine or dual-fuel engine,characterized in that the combustion gas (G) is fed in uncontrolled fashion to the gas valve (1) independently of the operating state of the gas engine or dual-fuel engine. The invention furthermore relates to a gas supply apparatus for a gas engine or dual-fuel engine in which combustion gas (G) is burnedwith combustion air (L), having a pressurized gas source and having a gas feed (10) to the gas engine or dual-fuel engine, wherein a gas valve (1) for the feed of combustion gas (G) into the combustion air (L) is arranged in the gas feed (10) upstream of the gas engine or dual-fuel engine, characterized in that control of the gas pressure in a manner dependent on the operating state of the gas engine or dual-fuel engine is not provided upstream of the gas valve (1).

The invention relates to a control valve for controlling a medium, especially a fuel, said control valve comprising: a sealing seat (2); a valve element (3), which is released on said sealing seat (2) and a closing passage (14); an actuator (4) for manipulating said valve element (3); and a bellows (5), said bellows being fixed on said valve element (3), wherein said The valve element (3) is arranged inside the bellows (5), wherein the outermost diameter (D1) of the sealing seat (2) is as large as the average diameter (D2) of the bellows (5).

The invention relates to a ground milling machine, in particular a road milling machine, finishing machine, stabilizer or surface mining machine, said ground milling machine having: a milling roller; a milling roller box with a scraping device, The scraping device forms the rear wall of the milling roller box in the working direction and is pivotable between a working position in which the scraping device closes the milling roller box and a maintenance position in which the scraping device closes the milling roller box. In the position, the scraping device opens the access to the inner cavity of the milling roller box; the locking device, the locking device can releasably fix the scraping device in the maintenance position; and the operating element, after manually operating the operating element, The locking device releases the scraper device again, wherein an operating element for actuating the locking device is provided on two opposite longitudinal sides of the ground milling machine.

The invention discloses a sharp tool structure capable of achieving rigidity adjusting at the far tool end. The problem that in the prior art, when rigidity adjusting is conducted on the sharp tool structure, hinge and plate spring deformation is prone to being caused is solved. The beneficial effects that design is reasonable and compact, and stable linear output of displacement is achieved are achieved. According to the following scheme, the sharp tool structure capable of achieving rigidity adjusting at the far tool end comprises a frame, multiple groups of lever amplifying mechanisms, a tool connecting block and fine adjusting mechanisms; the lever amplifying mechanisms are arranged in the frame, and the inner side of one end of each lever amplifying mechanism makes contact with or isconnected with the end of a driver; the tool connecting block is used for being connected with a tool and connected with the other ends of the lever amplifying mechanisms through first flexible hinges, and flexible guiding mechanisms are arranged between the two sides of the tool connecting block and the frame; and the fine adjusting mechanisms are arranged in the manner of penetrating through theframe, and the fine adjusting mechanisms penetrate through the ends of the frame and make contact with the lever amplifying mechanisms to achieve the purpose of adjusting the rigidity of the sharp tool structure at the far tool end.

The invention relates to a control device for an exhaust gas turbocharger, the control device having an exhaust gas guide section that can flow through, the exhaust gas guide section having a bypass channel for bypassing the exhaust gas guide a turbine rotatably arranged in the segment; and an adjustment arm (3) for receiving a valve element (2) arranged to open or close the flow cross-section of the bypass passage, wherein The adjusting arm (3) is accommodated movably in the exhaust gas guide section, and a spring element (14) is provided therein for at least securing the positioning of the valve element (2) on the adjusting arm (3) . According to the invention, the spring element (14) is designed in a radially slidable manner for reducing the adjusting force.

The invention discloses a device for adjusting the magnetic force of a printing magnetic table in cooperation with an adjusting screw and a cylinder element, which comprises a cylinder element installed at the bottom of a magnetic table support body and a rocker arm pivotally connected to the magnetic table support body; the bottom of the rocker arm The end is connected with the central axis of the cylinder element through double clevis, and the top of the rocker arm is connected with the magnetic table. The magnetic adjustment device also includes a gear set installed on the outer wall of the side beam, a transmission rod connected with the driving gear in the gear set, and an adjusting screw connected with the driven gear in the gear set; one end of the adjusting screw is screwed on the driven gear In the threaded hole, the other end is connected to the bottom end of the double clevis through an anti-wear device. Through the above-mentioned technical solution, a small adjustment force applied to the transmission rod from the outside can drive the adjustment screw to retreat or advance through the gear set, and the anti-wear device can transmit the power to the rocker arm without contacting the adjustment screw with the double clevis. Then the central axis is stretched or retracted to accurately and effectively adjust the magnetic force of the magnetic table.

The invention relates to a supercharger arrangement (1) with a variable geometry turbine (2), in particular an exhaust-gas turbocharger for a motor vehicle, having guide vanes (4) which are rotatably Fitted in the blade bearing ring (3) and has a top side (7) extending in a convex form from the profile nose (5) to the profile end (6). What is essential for the invention here is that the concave groove (9) is arranged on the bottom side (8) of the guide vane (4) at the profile nose (5). In this way, in particular an improved response behavior can be achieved.
