摘要:
An internal combustion engine includes an intake valve for controlling a cylinder intake port; an exhaust valve for controlling a cylinder exhaust port; first and second valve lifters coupled to the intake and exhaust valves, respectively, for cyclically opening and closing the intake and exhaust valves during normal engine operation; and an actuating device for contacting the exhaust valve and for operating the exhaust valve independently from the second valve lifter. The actuating device has a withdrawn position and a valve-contacting position. In the withdrawn position the actuating device is out of contact with the exhaust valve and in the valve-contacting position the actuating device is in contact with the exhaust valve. There is further provided an electromagnetically-operating setting device having an inoperative position assumed for a normal engine operation and an operative position assumed for an engine-braking operation. The actuating device is coupled to the electromagnetically-operating setting device such that in the inoperative position of the electromagnetically-operating setting device the actuating device is in the withdrawn position and in the operative position of the electromagnetically-operating setting device the actuating device is in the valve-contacting position. The electromagnetically-operating setting device further has a mechanism for operating the actuating device to open and close the exhaust valve when the actuating device is in the valve-contacting position.
摘要:
A transparent glass/plastic material composite pane, comprising at least one transparent plastic pane, at least one glass pane and according to demand an adhesion-promoting intermediate layer between the glass pane and the plastic pane, the glass pane being a glass film of a layer thickness of from 30 to 1,000 .mu.m.
摘要:
The invention relates to an electrode configuration for a device for generating a plasma. RF is coupled contactlessly via a capacitive coupling electrode disposed at the dark space distance into a carrier backside of a coating installation. Dark space shields on the coating side define the plasma zone and prevent the formation of parasitic plasmas. HF substrate bias voltage on the moving substrate carrier is achieved with a defined plasma zone and the development of parasitic plasmas is avoided.

The invention relates to a method for producing an adsorption heat exchanger, which is characterized by the following Steps: producing a heat exchanger structure; forming an adhesive layer (5) on the heat exchanger structure; filling the heat exchanger structure with a sorbent material (6.1); removing from the heat exchanger structure portions of the sorbent material that have bonded only weakly or not at all to the adhesive structure.
摘要:
Blends of olefin polymers and syndiotactic vinyl polymers are produced by the catalytic polymerization of olefins and aromatic vinyl compounds or methacrylate esters as vinyl compounds in inert diluents in the presence of a catalyst mixture of transition metal compounds, metalloxane compounds and metal alkyl compounds.The blends have a finely dispersed distribution of the blending components and are suitable for the production of films, sheets, fibers, panels, coatings, pipes, hollow objects, injection molded products and foams.
摘要:
In an internal combustion engine there is provided a cylinder head; a plurality of cylinder head bolts for securing the cylinder head to a cylinder block; at least one engine cylinder; at least two intake valves and two exhaust valves controlling the flow of gases into and from the engine cylinder. A plane defined by the intake valves and a plane defined by the exhaust valves extend at an angle of between 0.degree. and 15.degree. to one another and have an inclined orientation to the longitudinal engine axis. An overhead camshaft extends parallel to the engine axis and is situated in a zone bounded by the cylinder head bolts. Respective valve bridges interconnect the intake valves with one another and the exhaust valves with one another, and rocker arms connect respective cams of the camshaft with the valve bridges, whereby the intake valves are simultaneously operated by one cam and the exhaust valves are simultaneously operated by another cam.
摘要:
A variable displacement sliding vane pump comprising a pump body, inlet and outlet ports formed in said pump body, a drive shaft rotatably mounted in said pump body, a rotor driven by said drive shaft and co-axially aligned therewith, a plurality of radially extending vanes slidably disposed in said rotor, a pivot disposed in said pump body, a slide pivotally disposed on said pivot in said pump body and having a central axis eccentric to the axis of said rotor, a plurality of fluid chambers defined by said rotor, said vanes, and said slide that are successively connected to said inlet and outlet ports, a spring acting on said slide to urge said slide in one direction, a first chamber and a second chamber, each suitable for receiving a fluid pressure and each disposed between said pump body and an outer surface of said slide, the first chamber in fluid communication with a pump outlet discharge pressure, and a valve operable to selectively pressurize and depressurize the second chamber.
摘要:
A pane made of glass or plastic, whose optical degree of reflection can be controlled by switching between two different interference conditions. As a result, the transmissibility with respect to sun radiation can be reduced very efficiently and an excessive heating of glazed objects can be prevented. Preferred applications of the invention are the climate control of motor vehicles, rail vehicles, airplanes and buildings.
摘要:
A heated evaporator housing is provided at its inlet with an ultrasonic atomizer for reducing monomer to small droplets and a permeable porous body completely occupying a cross section of the housing between the inlet and the outlet. A vacuum pump and a reaction chamber for coating substrates are provided downstream of the outlet.
