Which mechanism causes decreased volumetric efficiency when hydraulic actuator encounters rapid decompression?

💡 Explanation

When rapid decompression occurs, the dissolved gasses in the fluid are liberated because the pressure reduction lowers their solubility threshold faster than bubble nucleation can occur, leading to cavitation and decreased volumetric efficiency. Therefore dissolved gas release results rather than other effects; viscosity increase, valve stiction, or diaphragm limit require different operational conditions.
