摘要： An electric actuator (14) is disclosed which comprises an electric motor (28) and a sensing means is provided which is adapted for detecting the angular position, and hence speed, of the rotor assembly (27) of the motor (20) by sensing the passing of a magnetic means which forms part of the rotor assembly. In one embodiment, the sensing means is adapted to measure the passing of an end face or an overhanging portion of the rotor magnet of the motor. The sensing means may comprise Hall effect or magneto-resistive sensing elements (62) and a shielding assembly (65) is also disclosed which both protects the sensing elements (62) from unwanted magnetic fields and increases the flux linked between the magnetic means and the sensing elements.

摘要： A valve assembly has first and second fluid inlets (16, 20) with a predetermined cross-section of flow, at least one valve member (44) prestressed by a first spring arrangement (106) in a first position in which the first inlet communicates with the second inlet (16, 20), and valve actuating means (42) that move the valve member (44) into a second position in which fluid communication between the first and second inlets (20) is checked. The valve arrangement is characterised in that the prestressing force of the first spring arrangement (106), the force exercised by the valve actuating means (42) on the valve member (44) and the cross-sections of flow of the fluid inlets (16, 20) are such that when a predetermined fluid pressure is applied to the second fluid inlet (20), the valve member (44) opens the second fluid inlet (20) until a fluid communication is established with the first fluid inlet (16).

摘要： A pinch sleeve (10) for connecting a metal-braid-coated pressure hose (14) with a connecting fitting (10) has a tubular metal basic body (40) having a first end towards the connecting fitting (10) and an opposite inlet end. At least in the region of the inlet end, the basic body (40) is fitted with a hollow cylindrical plastic insert (42) reaching at least as far as the inlet end of the basic body (40), the inside diameter of which in its axially inner end section in relation to the basic body corresponds at least approximately to the inside diameter of the basic body (40) which has a section axially connecting with the plastic insert (42). In its axially outer end section, the inside diameter of the plastic insert (42) increases continuously towards the axially outer end to prevent notch effects. The low coefficient of friction of the plastic insert (42) in relation to the metal braid coating of the pressure hose (14) provides a considerably lengthened useful life for a pressure hose (14) subjected to vibration.

摘要： An optical displacement sensor is used to measure the rotary displacement between two shafts (2, 4) which rotate together. By connecting the shafts (2, 4) together by means of a torsion bar (6), the sensor may be used to measure transmitted torque. The sensor comprises first and second coaxial discs (10, 12) mounted on the shafts (2, 4) and having slots (16, 18) formed therein. A light source (20) directs light through the slots (16, 18) onto an array (22) of photodetectors and a data processor (24) determines the displacement or torque from the positions on the array (22) of images of the slot edges.

摘要： In a brake servo housing (10), a first chamber (12) is separated by a movable wall (16) from a second chamber (14) which is permanently connected to a vacuum source. In an inoperative position, a first controlled valve (20) interconnects the two chambers (12, 14) and separates them from an ambient air inlet (38). When it is operated, this valve (20) separates the two chambers (12, 14) and connects the first chamber (12) to the ambient air inlet (38). The housing (10) also contains a pressure chamber (42) having a compressed air inlet (46) connectable to a second controlled valve (50) and connected to the first chamber (12) in order to fill the latter with compressed air. Between the first controlled valve (20) and the ambient air inlet (38) there is a check valve (82) which allows ambient air to flow freely to the first controlled valve (20) but prevents compressed air from escaping into the environment. Thus a rapid build-up of pressure in the first chamber (12) is ensured when required.

摘要： A fuel pumping apparatus of the rotary distributor type has a pumping plunger (14) mounted in a bore (13) in the distributor member and a cam ring (24) operable to move the plunger inwardly in timed relationship with the associated engine. The cam ring is positioned by a fluid pressure operable piston (25) contained within a cylinder (26). The apparatus includes a further piston (31) mounted in a further cylinder connected to the first mentioned cylinder, the further piston being biased by a pre-stressed spring (32). A stop is provided to limit the movement of the further piston against the action of the spring which yields to limit the fuel pressure developed by the plunger during the initial inward movement.

摘要： In an assist device housing (10), two chambers (12, 14) are separated by a movable wall (16) which is connected to a valve housing (22). The latter contains a movable sealing member (60) to which are allocated a first valve seat (24) formed in the valve housing (22) and a second valve seat formed on a movable valve body (30). The valve body is axially movable on a piston (42) and forms the armature of an electromagnet (40) arranged inside the valve housing (2) in such a way that, when excited, it moves the valve body (30) away from the sealing member (60) against the force of a valve spring (38). The piston (42) is axially movable in the valve housing (22) and transmits actuating forces from an actuating member (44) to a force transmission member (50). On the piston there is a stop element (52) which extends outwards with axial clearance through radial recesses (34, 36) in the valve body (30) and the valve housing (22) and, when the actuating member (44) is not actuated, defines a shared inoperative position of the valve body (30) and the piston (42) by contacting a stop (54) formed on the assist device housing (10). In this inoperative position the valve spring (38) holds the valve body (30) against the stop element (52) and, at the same time, the second valve seat (32) against the sealing member (60).

摘要： A fuel pump for supplying fuel to an engine includes a rotary drive shaft (12) having an enlarged portion (18) through which the rotary part of the pump is driven. The pump also has an annular cam ring (17) which is angularly adjustable within the pump housing to vary the timing of fuel delivery. The pump includes a transducer (31) having pole pieces (33, 34) which are located in close proximity to the elongated portion (18) of the drive shaft. The pole pieces form part of a magnetic circuit including a magnet and the pole piece (33) and the adjacent surface of the portion (18) are shaped so that the flux in the magnetic circuit varies in a cyclic manner as the shaft rotates. The pole pieces and magnet are mounted on the cam ring (17) and the transducer includes a former (37) carried by the housing of the pump and upon which is wound a winding. The former surrounds a part of the magnetic circuit and the former and the part of the magnetic circuit are shaped so as to allow angular movement of the cam ring.
