wpust

Wpust is a Polish term with multiple meanings in technical contexts, and its exact sense depends on the domain being discussed. In mechanical engineering, a wpust refers to a slot or groove cut into a shaft, hub, pulley, or gear to receive a mating element, most commonly a key (klucz). This keyway locates the component axially and enables torque transmission from the shaft to the connected part. Wpustes can be through slots or blind slots, and their tolerances and fit influence whether the key fits loosely or tightly. Manufacturing methods typically include milling and broaching, followed by finishing to remove burrs. In assembly, the wpust and the key form a standard method for coupling components and transmitting rotational motion.

In fluid systems, wpust denotes an inlet or port through which a fluid or gas enters a device, such as an engine air inlet, a pump inlet, or a duct opening. The design of a wpust—its size, shape, and location—depends on flow requirements, pressure conditions, and the overall system architecture.

Usage notes: the term is polysemous, so authors often specify the domain to avoid ambiguity. In Polish technical literature, “wpust” may describe either a mechanical slot for a key or a physical inlet port, and the intended meaning is typically clear from context.
