    摘要： A pump (1) comprising a lubricant reservoir (3) which feeds at least one pumping element (2), the reservoir (3) being delimited by a base (4) in correspondence with which, inside the reservoir (3) there is a rotating spatula (5) featured, equipped with at least one blade (5A) which, by rotating over the base (4), conveys the said lubricant towards an intake (2A) in the said pumping element (2) pushing the said lubricant through a plurality of passages (4A) made in the surface of the said base (4).

    摘要： The invention relates to a lubricant dispenser comprising a storage container (1) filled with lubricant and a pump (2) which is connected to or can be connected to the storage container (1) and by means of which the lubricant can be pumped out of the storage container (1). The pump has a pump housing (3) with an inlet opening (4) and an outlet opening (5), a piston (6) which is movably guided in the pump housing (3) in a linear manner, and a drive (7) which acts on the piston (6). The pump housing (3) of the pump (2) is connected to or can be connected to the storage container (1), and the piston (6) can be raised or lowered cyclically by the drive (7) in order to pump a lubricant from the inlet opening (4) to the outlet opening (5). The lubricant dispenser is characterized in that the piston (6) is designed in a stepped manner with an upper piston surface (10) which delimits an upper displacement chamber (8) and a lower piston surface (11) which delimits a lower displacement chamber (9) and is reduced compared to the upper piston surface (10). The upper displacement chamber (8) adjoins the inlet opening (4) via a first valve (13), and the first valve (13) is loaded or can be loaded into a closed base position. A through-opening (12a, 12b) which connects the upper displacement chamber (8) to the lower displacement chamber (9) with the interposition of a second valve (14) is arranged in or on the piston (6), and the lower displacement chamber (9) transitions into the outlet opening (5) via an outlet channel (16). When the piston (6) is lowered as the result of a negative pressure in the upper displacement chamber (8), the first valve opens (for example against a spring force), and lubricant is suctioned out of the storage container into the upper displacement chamber (8), but the second valve (14) closes and lubricant is pushed out of the lower displacement chamber (9) into the outlet channel (16). When the piston (6) is raised, the first valve (13) closes, but the second valve (14) opens in the piston (6), and lubricant both flows from the upper displacement chamber (8) into the lower displacement chamber (9) and is pushed from the lower displacement chamber (9) into the outlet channel (16).

    摘要： In an electric oil pump device including a drive power source and a gear device through which a vehicle drive force of the drive power source is transmitted, the electric oil pump device delivering a lubricant oil to the gear device, and generating a hydraulic pressure for controlling the gear device, a pump portion for delivering the lubricant oil, a motor portion for operating the pump portion, and a driver portion for controlling an operation of the motor portion are included. The pump portion, motor portion and driver portion are formed integrally with each other, or the driver portion is disposed adjacent to the motor portion. The pump portion and a part or an entirety of the motor portion are disposed within a space defined by an oil pan and a casing accommodating the gear device, and the driver portion is disposed outside the casing and the oil pan.
