The first (8) and the second toothing system (16) are each made of at least one tooth (10, 18) and a tooth space (12, 20). The toothing systems (8, 16) are in engagement with each other such that working chambers (24) are formed by means of the meshing of the teeth (10) of the first toothing system (8) and the teeth (18) of the second toothing system (16), wherein volumes that are formed by the working chambers (24) are changed by means of the meshing of the teeth (10, 18).

摘要： Delivery units are already known, having a drive rotor and an output rotor driven by the drive rotor, which are rotatably mounted in a rotor housing and interact in a meshing manner via spur toothing in each case, at least one of the two rotors being axially adjustable and, on the rear side thereof, facing away from the other rotor, having a compensating pressure applied via a compensation channel. The compensating pressure acts firstly counter to the axial compressive forces which arise in the working chambers formed between the rotors, and secondly compensates for the forces which would force the two rotors apart. This ensures that the distance between the rotors does not change. The compensating pressure frequently corresponds to the pressure on the pressure side of the delivery unit, which means that the forces on the rotors are considerably higher than necessary. This leads to increased friction in the bearings and between the rotors. The rear side of the rotors can also be supplied via slot flows. This has the disadvantage that an undefined compensating pressure is established, which depends on the leakage flows which flow into the space or out of the space behind the rotor. In addition, in this embodiment the compensating pressure does not have the ideal value for low-friction operation. In the delivery unit according to the invention, a defined compensating pressure is established on the rear side of the axially adjustable rotors. The invention provides for a control valve (14) to be provided, which sets the compensating pressure to a predetermined value between a pressure on the pressure side and a pressure on the suction side.
摘要翻译：输送单元是已知的，具有由驱动转子驱动的驱动转子和输出转子，所述驱动转子和输出转子可旋转地安装在转子壳体中并且分别通过正齿轮啮合地相互作用，两个转子中的至少一个轴向地可调节的，并且在其背面上背离另一个转子，具有通过补偿通道施加的补偿压力。补偿压力首先抵抗在转子之间形成的工作室中产生的轴向压缩力，其次补偿将迫使两个转子分开的力。这确保了转子之间的距离不会改变。补偿压力通常对应于输送单元的压力侧上的压力，这意味着转子上的力比必要的高得多。这导致轴承和转子之间的摩擦增加。转子的后侧也可以通过槽流供应。这具有的缺点是建立了未定义的补偿压力，这取决于流入空间或流出转子后面空间的泄漏流量。另外，在该实施例中，补偿压力对于低摩擦操作而言不具有理想值。在根据本发明的输送单元中，在轴向可调节转子的后侧上建立限定的补偿压力。本发明提供了一种控制阀（14），其将补偿压力设定在压力侧的压力与吸力侧的压力之间的预定值。

摘要： There are already known pump units comprising a drive shaft (2) and a rotatably arranged rotor (3) that is driven by the drive shaft (2), wherein the drive shaft (2) has an inclined sliding surface (4) on an end side, which permits the rotor (3) to move back and forth by its rotor axis (5) about a drive axis (6) of the drive shaft (2), wherein the drive shaft (2) has a first bearing section (18) facing towards the the rotor (3), and a second bearing section (19) facing away from the rotor (3). The first bearing section (18) of the drive shaft (2) is arranged in a first sliding bearing (20), and the second bearing section (19) is arranged in a second sliding bearing (21). The load-bearing capacity of the sliding bearing facing towards the rotor (3) is limited up to a predetermined working pressure in the pump unit. In the pump unit according to the invention, the load-bearing capacity of the sliding bearing (20) facing towards the rotor (3) is increased. According to the invention, the diameter of the first bearing section (18) of the drive shaft (2) and the first sliding bearing (20) is respectively larger than the diameter of the second bearing section (19) and the second sliding bearing (21).
