    Abstract: A modular multi-pump system is provided. The modular multi-pump system may comprise a plurality of modular pump systems (90; 390-1, 390-2, 390-3). A modular pump system (90; 390-1, 390-2, 390-3) may comprise a pump (30), at least one backpressure orifice (32, 34), a pressure regulating valve (40) (PRV), and a mix valve (50). The pump (30) may receive and pump a fluid through the modular multi-pump system. The at least one backpressure orifice (32, 34) may set a desired fluid output pressure for the fluid flow. The pressure regulating valve (40) may maintain modular pump system fluid output pressure in response to being in a balanced position, and may initiate fluid flow transition to the next modular pump system (90; 390-1, 390-2, 390-3) in response to being in a transition position. The mix valve (50) may prevent fluid flow from the next modular pump system (90; 390-1, 390-2, 390-3) in response to being in a first position, and enable fluid flow from the next modular pump system (90; 390-1, 390-2, 390-3) in response to being in a second position.

    Abstract: The present invention relates an intake valve actuating system (13), specially to reciprocating machines, the use of said system in compressors and a compressors starting method, promoting advantages on the compressors starting, minimizing the power needed on said reciprocating machines. Specially, the present invention comprises a controlled actuating mean (1) actuating an intake valve (13), by a coil (7), while a piston (12) starts its reciprocating movement. The intake valve (13) can be displaced, at the expense of the reciprocating movement of the piston (12), displacing a relief spring (10), avoiding overloading the coil (7). The present invention is situated on field of Mechanical Engineer, more precisely on the area of Flow Machines.

    Abstract: An air compressor comprises: a housing (60), a motor (691) coupled onto the housing (60), a transmission mechanism (69), a cylinder (61) extending from the housing (60) and having an air reservoir (63), a plurality of ducts (64,65) installed at the air reservoir (63), and a piston (62) installed in the cylinder (61) and driven by the transmission mechanism (69) and the motor (691) to input compressed air into the air reservoir (63) and output the compressed air from the ducts (64,65) of the air reservoir (63). The air compressor further comprises a pressure gauge (M) having an over-pressure protection unit which is directly coupled to one of the ducts (64,65). The pressure gauge (M) measures and indicates a change of the pressure value and, if the pressure value reaches a predetermined maximum safety pressure value, discharges air through an over-pressure protection unit.
