摘要：
A vest (11) for a human body (14) has an air core (36) coupled to a pulsator(12) operable to subject the vest (11) to pulses of air which applies andreleases high frequency pressure forces to the body (14). The pulsator (12)has two diaphragms (89, 91) connected to a brushless electric dc motor (118)with rotary to reciprocating linear motion transmitting mechanisms (116, 117)comprising scotch yokes having anti-lash assemblies (200, 218) operable togenerate air pulses in an air pulsing chamber (87). The diaphragms (89, 91)also increase the pressure in a manifold chamber (88). A check valve (99)connects the manifold chamber (88) with the pulsing chamber (87) to allowpressurized air to flow from the manifold chamber (88) into the pulsingchamber (87). An air flow control valve (167) in communication with themanifold chamber (88) is used to adjust the pressure of the air in themanifold (88) and pulsing chambers (87). A programmable motor controller (165)adjusts the duration of operation and speed of the motor (118) to vary theoperational time and frequency of the air pulses.
