The invention discloses a button controlled flow shower head. The shower head comprises three parts, namely a body fixing part, a surface cover water outlet part matched with a body, and a functional control part, wherein a V-shaped ring for sealing is arranged on each of a left control shaft and a right control shaft, the left control shaft and the right control shaft are arranged in a circular hole of a main pipe and fixedly connected by a screw sleeved with an O-shaped ring, and the left control shaft and the right control shaft can rotate in the circular hole; a spring is arranged on a button inner rack, and the button inner rack is arranged on buttons and can move forwards and backwards; the other spring is arranged at the bottom of the button inner rack, then the button inner rack is arranged on the main pipe, and the buttons drive the button inner rack to move vertically; a small cover plate and the O-shaped ring are respectively arranged on the end faces of the main pipe; and the functional control part is arranged between a water inlet pipe and a water entry pipe of the body fixing part, and the O-shaped ring is used for sealing the functional control part, the water inlet pipe and the water entry pipe. 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 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 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.
