摘要： An exhaust gas return control system for internal combustion engines is proposed, which includes an apparatus case 19 in which a servo motor 45 is disposed, which through a driving gear 47 and a driven gear 36 drives a threaded spindle 35 on which an exhaust gas valve closing member 41 is disposed which cooperates with an exhaust gas valve seat 27 on a tubular exhaust gas valve seat body 24. The apparatus case has on the side of the servo motor an air inlet of an air duct 13, 15 leading to the air induction pipe 2 of the internal combustion engine and, on the exhaust gas valve side, an exit from this air duct through which the proportionally fed exhaust gas is also led. A guiding collar 44 diverts the entry of the exhaust gas to an exhaust pipe 30 provided for the purpose. Also, in one embodiment an air valve seat body 21 radially surrounding the exhaust gas valve seat body 24 is provided, which cooperates with an air valve closing member which can be actuated simultaneously with the exhaust gas valve closing member and through which bypass air branched off upstream from a throttle valve 3 in the air induction pipe 2 can be proportionally fed.

摘要： A Diesel engine distributor-type injection pump has a vane pump (3) providing fuel under pressure to an injection pump system formed by two pistons (17) pressed towards each other by a cam track (26) to provide fuel under injection pressure to fuel injection plug connectors (28, 29) when the radial position of a duct (27) in the bore of the rotating shaft (2) matches a connecting duct (28) of a respective injection outlet. To provide for precise timing of fuel being injected, pressurized fuel is drained under control of a slider valve (FIG. 1: 38, 39; FIG. 2: 72, 74) connected through a communicating duct (32, 42, 71) to the slider valve. The slider valve is operated by a piezoelectric positioning element (FIG. 1: 61; FIG. 2: 76) which moves the spool (74, 39) of the slider valve; in one embodiment (FIG. 1), the piezoelectric element operates a piston (53) having a substantially larger diameter than the end faces of the spool (39) to provide for excursion amplification; in another embodiment (FIGS. 2, 4-8), the piezoelectric elements are bending elements and thus provide for larger excursion.

摘要： To suppress spurious oscillations of a membrane-suspended plunger forming a valve body cooperating with the valve seat, the plunger is formed with a blind bore into which a small piston extends, with slight clearance, the bore and piston forming a damping cylinder-piston arrangement which includes additionally a damping fluid so that, upon movement of the plunger as the consequence of energization of a solenoid, the damping cylinder-piston system will suppress such oscillations while still permitting positive movement of the plunger and hence seating the operation of the valve with minimum force due to the membrane suspension thereof.

摘要： An injection valve which serves to inject fuel into the intake manifold of a vehicle engine. The valve has a spin chamber upstream of the injection port which can be connected with a return line to the supply pump providing the pressure, for the purpose of continuous maintenance of a spinning motion of the fuel. The closing body of the valve has a projection extending into the injection port and beyond the valve seat which prevents drip formation when the valve opens.

摘要： A double-arm, sharply angled lever is pivoted at its fulcrum to the drive element of the clutch, and has one arm extending generally in a direction to the center of rotation of the driven element, and biassed by a spring force to engage the driven element. The fulcrum or pivot point of the double-arm lever is so placed with respect to the engagement surface of the arm of the lever with respect to the driven element, that the resulting force vector, resulting from the perpendicularly acting engagement force of the arm of the lever, in essentially radial direction, and the frictional force between the circumference of the driven element and the arm of the lever are located slightly behind the pivot point of the lever when the clutch is engaged, to effect self-locking of the lever arm against the driven element. The second arm of the lever carries, or is formed with a centrifugal weight and, upon rapid rotation of the driven element, moves the lever to swing outwardly, against the force of a spring, self-locking being overcome when the resultant force vector passes through and then in advance of the pivot point of the lever, providing for smooth engagement and disengagement of the clutch with positive, self-locking when the clutch is engaged. The position of the pivot or fulcrum point of the lever with respect to the resulting engagement force provides a toggle action, with binding force on one side of the toggle, and smooth, release/engagement at the other.

摘要： Electric control of a hydraulic valve control system is obtained by providing hydraulic fluid to form a hydraulic plug between a cam follower in engagement with the camshaft of the engine and a valve stem (11), the hydraulic plug or hydraulic fluid being retained in a chamber which, under control of an electrically operated valve (20, 25; 38), can establish communication to a drain line (19, 47). For rapid movement, the valve can be clamped in closed position by a piezoelectric column (FIG. 1: 28) to prevent drainage, and, upon clamping release of the column, permit drainage, and hence release of the "hydraulic plug", and thus provide for closing action of the valve under operation of a valve spring (13) to thereby shorten the open-time of the valve (FIG. 2, compare curves 31, 32, 33). A spool slider valve can also be used, the position of which is controlled by a pilot valve (FIG. 3: 40, 57, 64) in which a piezoelectric element moves a piston (57) which establishes pressure differential on a slider spool (42) which, respectively, connects the hydraulic plug to a drain (47) or prevents drainage, thus transferring movement of a cam (3) from the camshaft to the cam follower (4) and hence to the valve stem (11).

摘要： To provide for extremely rapid operating conditions of the valve in an electrically controlled fuel injection system, that is, valve operation in the order of 10.sup.-5 seconds, for example, a pump (2, 62) provides pressurized fuel, and two, in push-pull operating valves (4, 64; 5, 65) are provided, in which one of the valves (4, 64) controls initiation of fuel injection, and the other one of the valves (5, 65) controls termination thereof; each one of the valves uses a spring-loaded valve element (18, 38", 38, 38'), operated by the pressure of the fuel to be injected, the valve elements being retained in a predetermined position by an electrically controlled operating unit (27, 47"; 47, 47') which has a positioning element operating in a positioning path having at least a component which is perpendicular to the operating direction of the valve element and which, as commanded by the control voltage applied thereto, clamps the valve element in a predetermined position, and thus prevents movement of the valve element even though fluid pressure is applied thereto. Preferably, the electrical control element is a stack of piezoelectric disks which, upon energizaton, expand in axial direction and press a clamping stem (26, 46"; 46, 46') the movable valve element (18, 38", 38, 38') in an operating bore of the valve unit or housing (16, 36).

摘要： A centrifugal frictional clutch is constituted by a rotary housing supporting for rotation a weight lever actuated by the centrifugal force and being biased by a spring against the latter. The weight lever pivotably supports a coupling jaw which cooperates with a frictional surface of a coupling disk. The resultant normal frictional force F.sub.N forms with the line connecting pivot points of the jaw and of the lever a design angle .gamma. which corresponds to the angle of the static friction. The biasing spring, the jaw and the weight lever are arranged within the range of the coupling disk. Preferably, the clutch includes an additional disk having a smaller diameter and coupled via a free-wheel coupling to the first coupling disk to act as a double speed clutch.

摘要： An electromagnetically operable valve having a fuel inlet connecting piece which is surrounded by a magnet coil and is used as a core, at least a part of the valve is surrounded by a plastic sheath on which an electrical connecting plug is integrally formed. In the novel valve, the electrical connecting plug is injection molded at the same time as the extrusion coating of the magnet coil and thus forms an independent plastic injection molding. Only one valve extrusion coating tool is now required for different embodiments of the electrical connecting plug, resulting in greater flexibility in the assembly line. The valve is used as an injection valve for fuel injection systems.
