US Patent:

41106474, Aug 29, 1978

Filed:

Jan 13, 1977

Appl. No.:

5/759170

Inventors:

Ralph G. Eslinger - Elyria OH
John M. Nicolson - Elyria OH

Assignee:

The Bendix Corporation - Southfield MI

International Classification:

H02K 1920

US Classification:

310168

Abstract:

A wheel speed sensor for a vehicle adaptive braking system is installed within the vehicle hub cap so that the hub cap and speed sensor assembly are installed on the vehicle wheel as a unit. The speed sensor includes a rotor assembly which is rotatable with the hub cap, and a stator assembly which includes a bearing which slidably and rotatably receives a spindle which is integral with the hub cap. A tang projects from the stator assembly and is received in a corresponding slot on the vehicle axle to prevent relative rotation between the sensor assembly and the axle. A spring is provided which rotates with the hub cap and which yieldably urges the stator into engagement with the end of the vehicle axle. Consequently, the hub cap and sensor assembly are installed and removed from the vehicle as a unit, thereby facilitating installation of the sensor assembly since the air gap between the stator and the rotor may be set at the place of manufacture of the sensor assembly.

Abstract:

Compressor inlet control devices control the pressure level at the inlet of a compressor (18) which is operated by an engine (10) equipped with a turbocharger (12) that maintains the intake manifold (16) of the engine (10) at pressure levels greater than atmospheric for most engine operating conditions. A valve (20) limits the pressure level at the inlet of the compressor (18) to a predetermined pressure level to prevent damage to the compressor (18). The valve (20) includes a pressure differential responsive piston (36) which responds to the pressure level at the valve inlet (52) to close a pair of valve members (60,62) to terminate communication between the valve inlet (52) and outlet (54) when the pressure level at the inlet (52) exceeds the predetermined pressure level, and to initiate communication between the inlet (52) and outlet (54) when the pressure level drops below the predetermined pressure level.

International Classification:

US Classification:

Abstract:

An air supply system for a vehicle includes an internal combustion engine that powers the vehicle and a compressor that receives air from the intake manifold of the engine or from an air filter. The compressor operates in either a loading or unloading mode and supplies air to the vehicle braking system. During the loading mode, air flows from the compressor through a dryer and is stored in a reservoir that supplies air to the brakes when the brakes are actuated. The dryer removes moisture and contaminants from the compressed air before the air is stored in the reservoir. A valve independently controls the compressor and dryer. A first sensor produces a fueling status signal in response to monitoring the fueling status of the engine and a second sensor produces a reservoir pressure signal in response to measuring the air pressure in the reservoir. An electronic control unit receives the reservoir and fueling status signals and produces a pressure comparison signal in response to comparing the reservoir pressure signal to a predetermined pressure signal. The electronic control unit controls the compressor based on the compressor and fueling status signals and controls the dryer based on the reservoir pressure signal.

International Classification:

F16J 1516

US Classification:

277 81P

Abstract:

A seal assembly (54) for closing a cavity (55) between a rotor (24), a bearing retainer (38) and a crankshaft (80) to retain a fluid therein for lubricating bearings (48, 50, 90) associated with the crankshaft (80). Seal assembly (54) has a disc (72) with a first resilient member (56) that engages the rotor surface (44) and a second eccentrically positioned resilient member (62), that engages surface (65) on bearing retainer (38). Disc (72) which is attached to crankshaft (80) rotates with ring gear (36) around pinion (32) to maintain a sealed cavity (55) even though the first and second resilient members (56 and 62) rotate on their respectively sealing surfaces (44 and 65) with different revolutions per minute.

US Classification:

Abstract:

A rotary air compressor includes a rotor which rotates within a housing and controls communication through inlet and outlet ports provided on the housing and compresses air communicated through the inlet port for delivery to the outlet port. The inlet and outlet ports are provided with check valves controlling communication therethrough. After the rotor rotates through a dead-center position, the check valves in both the inlet and outlet ports are closed. The rotor then rotates into a position in which the apex seals carried by the rotor wipe across the inlet and outlet ports simultaneously, thereby opening a communication path bypassing the apex seals so that the pressure levels in the chambers across the rotor are equalized. As the rotor continues to rotate, air is compressed and communicated to the outlet port.
