Abstract: An internal compensation component (100) for an internal gear pump (1000) is disclosed. The component (100) is configured to be sandwiched between a pump cover (300) of the internal gear pump (1000) and a gear pair (200) of the internal gear pump (1000), and the component (100) includes: a floating side plate (110) and a floating sleeve (120) fixed at a side of the floating side plate (110) far away from the gear pair (200), a part of the floating sleeve (120) is configured to extend into an oil storage tank (310) of the pump cover (300), the oil storage tank (310) is configured to be communicated with a high-pressure oil area (I) of the internal gear pump (1000), and the floating side plate (110) is configured to press tightly against the gear pair (200) under the pressure of oil in the oil storage tank (310). An internal gear pump (1000) including the internal compensation component (100), and a forklift including the internal gear pump (1000) are also disclosed.
