    摘要: A standard motor vehicle having a pair of driving wheels (8), (9) powered by a drive shaft (10) through a differential (11) can experience difficulties when one of the two differentially driven wheels (8/9) loses traction. The differential (11) directs all of the power to the wheel that is slipping and the wheel with traction remains stationary. Various anti-spin devices have been developed but these often produce an abrupt transfer of all of the driving power to the wheel having traction. The anti-spin apparatus of this invention overcomes this problem and includes an electrical control circuit (24) and sensors (20), (21) for generating a slip signal representing the speed difference between the wheels (8), (9). The apparatus further includes a modulated hydraulic reducing valve (30), (110) for actuating the brake (15/15') on the faster rotating wheel (8/9) and a hydraulic modulating control valve (29) connected to the reducing valve (30), (110) and actuated by the slip signal. The reducing valve (30 ), (110) is modulated to proportionally vary the braking force applied to the faster rotating wheel in accordance with the difference in rotational speeds between the wheels (8), (9).

    摘要: A connector mechanism is provided to connect a spool in an air actuated valve to the diaphragm of an air actuating mechanism in order to permit rotational movement of the spool relative to the diaphragm. The connector mechanism includes a connector member having one end thereof firmly connected to the diaphragm and the other end thereof connected to one end of the spool and retained thereto by a retainer member which permits free rotation of the spool relative to the diaphragm during use of the air actuated valve.
