摘要:
An electromagnetically actuated valve of a hydraulic unit is received in pressure-tight fashion and mounted without complicated adjustment of the valve stroke. The valve comprises a hydraulic part and an electrical part. The hydraulic part is a pre-mounted unit with a stroke of a seat valve set before insertion into a receiving bore of a metal valve block. The hydraulic part is received in pressure-tight fashion in the valve block by a first swaged connection located between an inlet conduit and an outlet conduit of the receiving bore. A sealing ring that closes off the receiving bore is retained by a radially extending flange of a bushing slipped onto the hydraulic part. The flange is secured to the valve block by a second swaged connection. The hydraulic unit is usable for traction-controlled motor vehicle brake systems.

The invention relates to a hydraulic unit with a solenoid valve inserted into a receiving bore of a hydraulic block. With rigid fastening, the solenoid valve can rest under pressure against a circumference point of the receiving bore and when there is alternating stress on the solenoid valve during operation, the solenoid valve displaces material of the hydraulic block. In order to prevent this, a fastening device with a securing ring caulked in the receiving bore, includes a collar that is deformed into a circumferential groove of the solenoid valve leaving radial play.

A piston pump, which is provided as a return feed pump for a slip-regulated motor vehicle brake system. In order to simplify the manufacture, a sleeve in the form of a tubular piece is clamped between a fastening element which is inserted into the cylinder bore using a self-clinching technique, and the cylinder bore, and is thus sealed and fixed in place. In addition to the simple manufacture of the sleeve out of reasonably priced tubular material, the piston pump has the advantage of a sealing of the sleeve in the cylinder bore without a separate sealing element such as a sealing ring.

A hydraulic part of a magnet valve is received in a bore of a valve block. The hydraulic part is secured to the valve block with a calked heel of a securing bush that is slipped onto a guide sleeve of the hydraulic part. The securing bush rests on an annular shoulder of the guide sleeve and engages a jacket wall of the guide sleeve with a press fit, and one edge of the securing bush is adapted to a rounded-out throat between the jacket wall and an end wall of the annular shoulder by means of plastic deformation. A valve sleeve engages a portion of the bore of the valve block with a press fit. The calked heel, the plastically deformed edge of the securing bush, and the press fit of the valve bush seals that seal off against fluid are achieved without using additional rubber-elastic sealing means.

Multiposition valves are used for instance to interrupt a flow of pressure fluid that begins at a pressure source, such as a master cylinder, and leads to a consumer, such as a wheel brake. To that end, such multiposition valves have a valve seat, a valve seat closing body, an electromagnet which presses the valve closing body against the valve seat, and a valve opening spring, so that when the electromagnet is turned off, the valve closing body assumes an outset position spaced apart from the valve seat. To reduce noise production, especially when power is supplied in pulsed fashion to the electromagnet a further spring is provided that urges the armature in the direction of its outset position, so that when the valve opens, the armature can lead ahead of the valve closing body. The valve is advantageously usable in a hydraulic vehicle brake system where irritating noise production during operation is to be avoided.

The invention relates to an electromagnetic device, in particular for a slip-controlled, hydraulic vehicle brake system, having at least a first magnet valve which is closed in its currentless basic position and having at least a second magnet valve which is open in its currentless basic position, the first and second magnet valves being received in receiving bores of a valve block. The invention provides that the first and second magnet valves have structurally identical, one-piece valve housings, in each of which all the magnet valve components are received essentially without any axial protrusion, and that the total length of each of the first and second magnet valves is recessed in the receiving bores of the valve block, and that a nonferromagnetic spacer ring is disposed between a face end, pointing toward the valve seat, of at least one magnet coil and a dividing plane between this magnet coil and the associated pole piece.

An apparatus for smelting meltable substances, particularly ore concentrates. A transfer element joins the cyclone discharge to the furnace and is arranged between the melting cyclone and the furnace. In this way, the fitting, particularly the re-fitting of an open-hearth furnace with a melting cyclone can be significantly simplified; or, on the other hand, the melting cyclone can be very easily dismantled for the purpose of repair or can be replaced by another melting cyclone in a relatively short time, namely without a significant interruption of furnace operations.
摘要:
A method and apparatus for reducing molten metals and/or slags thereof which involves top-blowing at least one reduction gas stream wherein fine grained coal or coke particles and injected for covering the surface of the molten metal beyond the blow impression formed by the reduction gas stream. The particles of the stream are at least partially gasified into a carbon monoxide (CO) contained reduction gas stream before they hit the metal surface, so that a mixture of carbon monoxide and coke is blown onto the metal surface together with the reduction gas stream. The coke particles are then radially moved toward the outside of the blow impression at all sides to form a thin veil beyond the perimeter of the blow impressions.

A valve whose valve stroke must be adjusted is provided with a throttle bore. The valve has a guide tube open on the bottom with a press-fit in a valve body through whose through bore the valve closing member of an armature received in a guide tube is accessible for engagement by a scanner pin of a measuring tool. After adjustment of the valve stroke, a throttle insert is introduced into the throttle bore of the valve body, using a double-lipped cuff. While an inner lip seals off the throttle insert in the valve body, an outer lip of the cuff, in cooperation with a housing receives the valve and takes on the function of a check valve. The valve is suitable for anti-lock and/or traction-control systems of motor vehicle brake systems.
摘要:
A method and apparatus for the pyrometallurgical treatment of fine grained solids such as non-ferrous metal ore concentrates with an oxygen-containing gas wherein the solids are mixed with the gas to form a suspension which is blown through a nozzle into a reaction chamber such as a vertical melting cyclone. In the reaction chamber, the solids are brought to reaction and melted. The invention is concerned with injecting a particle stream through the reaction zone as a focused open jet having mass flow velocity of greater than 50 kg/m.sup.2.sec and having a linear speed of more than 35 m/sec. The particle stream is ignited by the hot combustion gases thereof or by a pilot flame. In a preferred embodiment of the invention, the particle stream is directed along a horizontal secant of the chamber to the opposite wall.
