  • Pumping device
    Patent number: 8313313
    Abstract: A pumping device (1) by which fluids held in a reservoir tank (9) can be pumped to a spray gun (11) in a metered manner, with a piston rod (5) mounted in a housing (2) in axially movable fashion, with a reciprocating piston (25) attached thereto, with a piston (7, 8) connected to the piston rod (5) and moved between a first and a second housing sections (3, 4), first and second pressure spaces (21,21?, 22, 22?) enclosed with the two housing sections (3,4), two pressure lines (17, 17?) in each of the housing sections (3, 4) such that emerge into one of the pressure spaces (21, 21? or 22,22?), a working medium (19) pressed through pressure lines (17, 17?) alternately into a pressure space, by means of which the piston (7, 8) is driven, with a diaphragm a central area (14) connected to the piston rod (5), and its outer area (15) connected to the housing (2), and a flexible ring area (16) between the central and outer areas (14, 15), and a pumping space (20) enclosed by the diaphragm (12, 13) and the housing (2),

  • Pumping device
    Publication number: 20090196771
    Abstract: In a pumping device (1) by means of which fluids (10) or pourable media held in a reservoir tank (9) can be pumped to a spray gun (11) in a metered manner, with a piston rod (5) mounted in a housing (2) in an axially movable fashion, with a reciprocating piston (25) attached to its free end, with a piston (7, 8) firmly connected to the piston rod (5) that can be moved between a first and a second housing section (3, 4), and by means of which a first and a second pressure space (21, 21?, 22, 22?) is each enclosed together with the two housing sections (3, 4), with two pressure lines (17, 17?) worked into one each of the two housing sections (3, 4) in such a way that they emerge into one of the two pressure spaces (21, 21? or 22, 22?), with a working medium (19) pressed through the pressure lines (17, 17?) alternately into the particular pressure space (21, 21?, 22, 22?), by means of which the piston (7, 8) can be driven, with a diaphragm (12, 13) with a central area (14) firmly connected to the piston rod (5)
