Abstract: A disc brake caliper comprises a housing (1) to be arranged to straddle a vehicule brake disc, a cover (2) attached to the housing, two thrust sleeves (8), which are connected to a brake pad (5) and which are axially movable in the housing, a cross bar (9) connecting the two thrust sleeves, and a lever (17) for transmitting a brake force from a brake cylinder (4), attached to the caliper, to a cross bar. Bearing tappets (20), parallel with the cross bar, are fixedly connected to the inside of the cover. The lever has a curved wedge (19) with two cylindrical surfaces (19', 19") in engagement with corresponding cylindrical surfaces of the bearing tappets and the cross bar, respectively. An adjuster mechanism (28) is arranged on a splined shaft (29) rotatably journalled in the bearing tappets.

Abstract: An inlet valve for an air drier between an inlet (35) from a compressor and an inlet bore (32) comprises an axially movable valve element (31), a spring (34) for biasing the valve element into a closing position against a seat (30'), and a valve element shoulder (31'), on which the pressure in the inlet is arranged to act in a valve opening direction. A sealing on the shoulder is in the form of a U-sealing (36) allowing air under pressure admitted to the underside of the valve element for urging the latter in a valve closing direction to pass by the sealing to the inlet but preventing flow in the opposite direction.

Abstract: A brake lever for an automotive S-cam drum brake has a toothed conical clutch (14) for transmitting torque in one direction between two coaxial members (4, 10) rotatably arranged relative to each other. Each tooth in this clutch is asymmetrical, its torque transmitting flank forming a greater angle with the normal than its opposite flank.

Abstract: A control arm arrangement for a road vehicle brake lever (1) comprises a control arm (3) pivotally connected to the brake lever and an anchor bracket (4) for attachment to an underframe part (2) of the vehicle. Facing ends of the control arm and the anchor bracket are provided with flanges (10, 11), so that the closely cooperating ends are U-shaped in cross-section.

Abstract: A brake lever for an S-cam brake has a worm wheel (3) engaging the S-cam shaft and a worm screw (4) meshing therewith. A clutch wheel (6) on the worm screw forms a clutch (8) therewith under the bias of a compression spring (9). A control movement is transmitted from an external reference point to the clutch wheel via a pinion (15), a carrier wheel (16) and a control screw (18), the common axis of these three parts being perpendicular to the worm screw, wherein the control screw meshes with the clutch wheel. The carrier wheel can be turned relative to the pinion an angular distance corresponding to the desired slack and is biassed to one end position by a torsion spring (17), which is also used to engage a one-way clutch (19) between the carrier wheel and the control screw.

Abstract: A retarding valve at a single-tower air drier for obtaining a controlled time for the flow of regenerating air from an air tank to a desiccant cartridge has a movable valve stem (7), which is provided with a piston (14) having a slightly smaller diameter than a chamber (13), in which it is movable in hydraulic oil (15), so that a narrow circumferential slit for the oil is formed. The valve stem with its piston is biased by a spring (16) from a position--at the beginning of each regenerating cycle--permitting flow through the valve to a position closing off flow through the valve.

Abstract: A wedge-type actuator for actuating drum brakes including guide rollers positioned between the wedge and a plunger that contacts the leading brake shoe. The guide rollers are carried between a guiding surface on the wedge and a guiding surface in the housing, to take up the reaction forces caused by the larger actuation forces needed to operate the trailing brake shoe. The disclosed arrangement provides more even braking forces, and thereby results in more even brake shoe wear.

Abstract: An air drier tower comprises a base part (2), a reservoir (1) attached thereto, and in the reservoir a cartridge (7) containing desiccant (8). The cartridge is composed of two halves (9,10) having circular walls extending into each other to form a winding air path through the desiccant. A spring (11) is arranged between the reservoir and the cartridge in order to exert a bias on one cartridge half and accordingly on the desiccant.

Abstract: An inlet valve for a two-tower air drier for directing an air flow from a central inlet to either tower through a respective one of a pair of opposed outlets. A valve body is axially movable between two valve seats and is provided with two annular flanges at such an axial distance from each other that at no position of the valve body will a flange cover any part of the central inlet. A restricted flow area past the flanges is accomplished as a flange moves towards its respective valve seat. The valve body is biased towards a neutral position by a helical compression spring, which is attached to the housing of the valve with its two ends and passes through an aperture in a stem of the valve body between the two flanges.

Abstract: The compressed air flow in an air drier is directed to either one of its two drying towers by a switch-over valve whose switch-over function is performed with the air drier unloaded by an unloader valve arranged between the air drier and a compressor. The unloader valve is caused to perform its unloading function not only at a predetermined pressure in an air tank to which the air is fed but also--by an electronic control device--after a predetermined time during periods of prolonged continuous air loading from the compressor through the air drier even if the predetermined pressure is not reached.

Abstract: A switch-over valve for directing a compressed air flow to either one of two drying towers of an air drier, the other one being vented to the atmosphere through the valve. A positively operated valve body is movable between two valve seats in a central chamber. A valve sleeve arranged at either side of the valve body is axially movable in a dividing wall between the central chamber and a respective outer chamber connected to the drying tower, is spring biased in a direction towards the valve body to a position where a radial valve sleeve flange in the outer chamber is in sealing contract with the wall, and is biased in the opposite direction by the valve body for lifting the flange from the wall and venting out the air from the outer chamber to the atmosphere through a channel in the wall.

Abstract: A switch-over valve for directing a compressed air flow to either one of two drying towers of an air drier, the other one being vented to the atmosphere. The valve is arranged in a partition wall between the two towers, a conduit to the valve being provided in the partition wall. A valve body is axially movable in a cavity in the wall between two positions sealing off either one of the outlets from the cavity and keeping the other one open. A control piston with a greater length than the valve body is axially movable in a bore in the valve body and is biased towards a neutral position by spring means.

Abstract: A wedge brake arrangement for drum brakes on heavy road vehicles includes a brake cylinder push rod (29), plungers (26) axially movable perpendicularly to the push rod, and force transmitting rollers (32) between parallel wedge surfaces at the end of the push rod and on the respective plunger. In order to obtain full control over the reaction forces from the plungers (26) at brake operation the push rod (29) is guided by the housing (25) of the arrangement in the plane of the plungers by means of guide rollers (35) between plane surfaces at the end of the push rod (29) and in the housing (25), respectively, the surfaces being parallel with each other and with the axis of the push rod.

Abstract: The invention relates to taximeter installations including mobile taximeter apparatus (2) coacting via radio (3, 4) with a central computer (1). Each taximeter (2) includes registers (15, 26) for collecting pulses relating to travelled distance and consumed time, the central computer (1) initiating periodic read-out (20, 21, 29, 30) of the register content, inter alia for fare price calculation. The central computer also sets a criterion frequency value, so that the pulses related to travelled distance are prevented by means of a circuit (9) from being stored in the register (15) when the frequency of said pulses falls below the criterion frequency, time pulses being stored in a register (26) when the criterion frequency is not attained by the travelled distance pulses.

Abstract: A control device for an instrument (10) attached to a vehicle wheel hub for recording the distance covered by the vehicle comprises a counting mechanism with several number-carrying wheels (25), a stamping mechanism (29,30) for stamping cards, a means (14) for advancing the number-carrying wheels of the counting mechanism in response to the distance covered, and a pendulum, the oscillation axis of which coincides with the vehicle wheel axle, and which by substantially standing still effects a relative movement in relation to the recording instrument. This movement is utilized for driving the means for advancing the number-carrying wheels of the counting mechanism via a gear unit (12). The means for advancing the number-carrying wheels of the counting mechanism comprise a feed hook (14), which is deformed permanently when number-carrying wheels of the counting mechanism are blocked, and thereby effects permanent closing of a first electric contact (14b-34).

Abstract: An overflow return tank, especially for receiving return fuel at internal combustion engines with fuel gauge, comprising a receptacle (20, 21, 22) with an inlet (23) located upwardly for a return flow and an outlet (25) and an air bleed hole (24), and with a float (30) located within the receptacle for controlling a valve (26, 36, 31a) located at the outlet of the receptacle. The valve comprises a soft, elastic diaphragm (36), which is connected to the float (30) and upon lifting of the float gradually exposes the outlet (25) by being bent, so that fuel can be taken out from the overflow return tank. Owing to the design of the valve only a small lifting force from the float is required, whereby the fuel amount in the overflow return tank can be maintained substantially constant even at great variations in the return flow. The overflow return tank, besides, can be given small dimensions.

Abstract: Two pairs of reciprocating pistons are selectively driven by a volume of fluid to be measured. The pairs are perpendicular to one another and connected to a crank for converting the reciprocating motion into rotary motion to magnetically drive a recording means. A valve is driven by the crank for selectively controlling the flow of the liquid into the piston bores. A conical member limits the stroke of one set of the pistons thereby adjusting the stroke of the meter. The member has a bimetal unit which automatically adjusts the stroke in response to the temperature of the liquid.
