    摘要： A pump, in particular a heavy-duty pump for pumping liquid or mixtures of liquids and particulate material, such as mud, proppant and concrete, said pump having at least one electric motor (15) coupled to a gear assembly (17), said gear assembly (17) in turn being coupled to at least one pinion (13, 14). The at least one pinion (13, 14) is meshing with two racks (9, 10) that are arranged in parallel on the same side of said pinion (13, 14) and said piston rod is arranged between the two racks (5, 6). The piston rod is operatively coupled to the set of racks (5, 6). The piston rod has at least one piston, or alternatively being coupled to a combined piston rod and piston (5, 6). The piston is received within a pump cylinder (1, 2) chamber.

    摘要： A variable displacement pump system can include a piston sleeve having at least a first inner diameter portion and a second in inner diameter portion and an actuator piston configured to be disposed within the piston sleeve. The actuator piston can have a first piston portion having a first outer diameter, and a second piston portion having a second outer diameter. The first outer diameter can be different than the second outer diameter. The first piston portion can be configured to seal to the first inner diameter portion of the piston sleeve. The second piston portion of the actuator piston can be configured to seal to the second inner diameter portion of the piston sleeve.

    摘要： A reciprocating compressor includes a cylinder that defines a compressing space and a discharge muffler configured to receive refrigerant compressed in the cylinder and to discharge the refrigerant. The discharge muffler includes a discharge muffler body and a discharge guide supported by the discharge muffler body. The discharge muffler body defines a discharge space configured to receive the refrigerant from the cylinder and includes a wall protruding from an inner circumferential surface of the discharge muffler body. The discharge guide is coupled to the wall and includes a pipe that defines a pipe inflow hole configured to receive the refrigerant from the discharge space and a pipe outflow hole configured to discharge the refrigerant. The discharge guide further includes a fixing bracket that couples the pipe to the discharge muffler body.
