Abstract

1,228,329. Preventing freezing of moisture in compressed air lines. ROBERT BOSCH G.m.b.H. 12 Nov., 1969 [13 Nov., 1968], No. 55266/69. Heading B1R. [Also in Division Fl] A pump for injecting anti-freeze into a compressed air line 26 comprises a pumping piston 6 reciprocable in a cylinder 5 in response to changes of air pressure acting on a motor piston 16 connected by a rod 7 to the pumping piston 6. Air pressure for actuating the motor piston 16 may be in the form of a fluctuating pressure supplied to a chamber 11 above the piston 16, or the pressure in the chamber 11 may be substantially constant, the fluctuating pressure then being applied to a chamber 18 below the piston 16. Anti-freeze enters the cylinder 5 through a pivot 4 connected to a reservoir 3 and is discharged past a valve 9 loaded by a spring 10. A stop 21 is adjustable to vary the stroke.
