摘要： The invention relates to an external gear pump (1), having a driving first pump gear (2) and having a second pump gear (3) driven by the first pump gear (1), which intermesh with each other to convey a fluid from a suction side (7) to a pressure side (8) of the external gear pump (1), wherein the first pump gear (2) and the second pump gear (3) each have a plurality of teeth (5, 6), each having a leading tooth flank (10, 12) leading in the rotation direction of the corresponding pump gear (2, 3), and a trailing tooth flank (10, 12), wherein the leading tooth flank (9, 11) of the first pump gear (2) interacts with the trailing tooth flank (10, 12) of the second pump gear (3) to drive the second pump gear (3) via the first pump gear (2). According to the invention, the trailing tooth flanks (10, 12) of the first pump gear (2) extend concavely at least in sections to form a fluid pocket (16) at at least one axial position in the radial direction.

摘要： In a gear pump, an outer rotor (40) and an inner rotor (45) are disposed in a rotor installation chamber (15) defined by a pump body (10) and a pump cover (20). A suction port groove (22) and a discharge port groove (31) are formed in at least one of the pump body (10) and the pump cover (20). A narrowing portion (60) is formed at a portion of a radially outer side wall portion (25) of the suction port groove (22), the portion being close to a terminal end wall portion (27) of the suction port groove (22). The narrowing portion (60) narrows the groove width in the radial direction. A pressurizing region (62) that pressurizes oil in the gear chamber (50) is formed between the narrowing portion (60) and the terminal end wall portion (27).

摘要： Provided is a simple fire truck that easily moves to a narrow fire occurred spot difficult for a car to enter by using a transfer wheel driven by a motor separately from a pump driven by an engine, the simple fire truck including: a depressurization groove that is formed between a chamber where a sealing unit receiving pressure of the pump is provided, and a suction hole, so as to depressurize a pressure of the chamber; a lubricating water supply unit for improving durability through lubrication and cooling by supplying lubricating water to an inlet of the chamber according to a vacuum pressure generated during an initial activation of the pump; and a rotor unit having a first protrusion at an end of a side of a rotor provided inside the chamber, and a second protrusion at a periphery of a shaft hole through which a rotation shaft penetrates. Accordingly, the simple fire truck easily moves to the narrow fire occurred spot difficult for a car to enter by using the transfer wheel driven by the motor separately from the pump driven by the engine, prevents a damage of the sealing unit by depressurizing a pressure transferred to the sealing unit by forming a groove between the chamber and a suction unit formed inside the pump, and improves durability of a positive-displacement pump through lubrication and cooling by using a lubricating water suction unit provided at a pump suction unit during an initial activation.
