    摘要: The present invention is directed to a reciprocating motor pump (1) suitable to generate compressed gas with a reduced noise level of at most 55 dB, wherein said pump (1) includes a pump casing comprising:—a gas inlet nozzle (3);—a gas chamber;—a cylinder chamber (4) comprising a piston (5);—an inlet valve (7);—an outlet valve (8); and—a gas outlet port (9); wherein gas enters the gas chamber (2) through a gas inlet nozzle—(3) of said gas chamber (2) and then flows from said gas chamber (2) to said cylinder chamber (2) to said cylinder chamber (4) through an inlet valve (7) of said cylinder chamber (4), whereby the ratio of the diameter of the opening of the gas passage of said inlet nozzle (3) to the diameter of the opening of the gas passage of said inlet valve (7) is 1:15 to 1:5.

    摘要: A method and apparatus are provided for feeding and folding sheets. Providing a folding blade having a free edge, reciprocably movable between a retracted position and a folding position, provided with blade surfaces adjacent to the free edge converging towards the free edge at a first angle in the folding position, and by further providing a pressing mechanism having pressing surface areas reciprocably movable between a retracted position and a pressing position, and enclosing in the pressing position a second angle larger than the first angle of the folding blade, allows an apparatus, having a pair of folding rollers and a sheet support, selectively to fold only an outer sheet from a set of sheets or to fold a set of sheets simultaneously.
