composition, in the centre of described control plunger (46), be provided with annulate shaft (49), both ends of the surface are provided with cushion blocking (50), on control plunger (46), be provided with the y shape seal ring (51) with sealing compensation function, at the upper setting-in of described middle annulate shaft (49), there is the slide block (48) of wear-resisting lubricating function, on the top of slide block (48), be provided with spill chamber (52), support spring (53) is placed in bottom, the outer face of described slide block (48) upper female chamber (52) and the closely moving contact mutually of pottery point part (47), at pottery, divide part (47), between control plunger (46) and slide block (48), form chamber P2, on source of the gas cover plate (45), there are free air diffuser (57) and chamber P1, on control valve body (43), there is free air diffuser (58), it and P1 chamber, the gas circuit of free air diffuser (57) and chamber P2 communicates, pottery point part (47) is arranged on the upper surface of control valve body (43), be provided with the kidney-shaped pore A11 of seal ring (54) above, 01 and B11, the joint of its underpart and control valve body (43) is provided with O-ring seals (55), at source of the gas cover plate (45), be respectively arranged with O-ring seals (60) with the fit engagement place of control valve body (43) and the fit engagement place of control cover plate (44-1) or remote control cover plate (44-2) and control valve body (43), on control cover plate (44-1), be provided with for the off-position valve opening (61) that off-position control cock (15) is installed, two ends at control plunger (46) are also arranged with air chamber C1 and D1,C, the exhaust governor valve (16) that off-position control cock (15) on described straight behaviour'"'"'s controllable type Windshield Wiper and band are eliminated the noise is arranged on respectively to be controlled the off-position valve opening (61) of cover plate (44-1) and swings in 011 screw of the main valve body (28) in reservoir (13), off-position control cock (15) is by controlling cover plate (44-1), off-position valve rod (65) and off-position handle (67) composition, off-position valve rod (65) is assemblied in off-position valve opening (61) by fastening assembly (71) is spacing, be provided
