Abstract: An oscillating-piston drive for a vacuum pump (1) with a piston (2), which presents has two piston sections (3,4) and an intermediate zone provided with a drive magnet (11). Cylinder sections (8, 9) slidingly receive the piston sections (3, 4). An annular recess (12) is defined between the cylinder sections (8, 9) at a central yoke (19). The recess provides space for movement of the drive magnet (11). An electromagnetic drive which surrounds the piston (2) includes yoke components (17, 18, 19) and coils (15, 16) situated to the sides of said central yoke. Negative influences on the delivery rate of the pump are reduced by a can (34) which delimits the recess (12) peripherally or by controlling the current supply to the coils, such that only one coil conducts current at a time.

Abstract: A linear compressor with an anti-collision device, which prevents a piston of the compressor from being brought into collision with a cylinder head and/or a suction valve even when the piston moves past an upper dead center position during an operation of the compressor. In one aspect, the anti-collision device may include a resonant spring, an elastic member spaced apart from the resonant spring, and a shock absorbing member having a central hole and set in the central opening of the elastic member. The central hole of the shock absorbing member may be tapered in a direction toward the cylinder head to have a first tapered surface, and the movable member may be tapered at a portion between the resonant spring and the anti-collision device, thus having a second tapered surface corresponding to the tapered surface of the central hole. Alternatively, the anti-collision device may include a first tapered surface formed on a skirt part of a cylinder by tapering the skirt part such that a diameter of a first tapered surface is reduced in a direction toward the cylinder head, and a second tapered surface formed on the piston so as to correspond to the first tapered surface of the cylinder.

Abstract: The invention relates to a method for operating a dosing pump, the pump being driven by an asynchronous motor, comprising a drive which converts the motor revolutions into pump strokes of a defined stroke frequency. The pump strokes are comprised of a pump suction stroke and of a pump delivery stroke. Pump strokes are continuously carried out during a dosing phase. The aim of the invention is to provide a solution concerning a dosing pump having an asynchronous motor drive, a frequency converter thereto, and a control unit which interacts therewith in which the dosing behavior is improved during the operation of dosing pumps having an asynchronous motor drive. The invention provides that, with each pump stroke, an electric alternating voltage having a first frequency is applied to the asynchronous motor during the pump suction stroke, and that the same electric alternating voltage having a second frequency which is lower than that during the pump suction stroke is applied to said motor during the pump delivery stroke.

Abstract: A hybrid electric hydraulic drive system, having a first cylinder (75) having a left chamber (32) and a right chamber (34) separated by a piston (22). A second cylinder (76) has a single or sole chamber (74) for receiving hydraulic fluid with the second cylinder enclosing a second piston (78). The second cylinder is substantially equal in length to the first cylinder and is rigidly attached to the first cylinder. A pump (14) is fluidly connected to the left chamber (32) by a first fluid passage (16) and is fluidly connected to the right chamber (34) by a second fluid passage (18). A third fluid passage (80) is directly connected to the right chamber (34) and to the sole fluid chamber (74) of the second cylinder (76). A first rod (30) is connected to the piston (22) and a second rod (84) is connected to the second piston (78). The first and second rods are connected by a connecting element so the rods move in unison. The volume of the sole chamber (74) is equal to the volume of the first rod (30) with the total fluid capacity of the system remaining constant during operation. An encoder (36) is electrically connected to a controller (40) which is electrically connected to a servo electric motor (10) which drives the pump (14).
