  "textContent": "A pump for anti-lock brake systems, which has inlet and outlet check valves (37;34) with improved structures capable of enhancing the operational performance of the pump while drawing or discharging brake oil into or from the pump. In the pump for the anti-lock brake systems, the outlet check valve (34) is a ring-shaped elastic body that is installed in an outlet path (42). The outlet check valve (34) is elastically deformed to discharge brake oil during an oil-discharging mode, and elastically restores an original shape thereof to prevent a reverse flow of the discharged brake oil during an oil-drawing mode. The pump thus prevents the reverse flow of the brake oil, reduces operational noise, and simplifies a process of producing elements of the pump, resulting in a reduction in the production costs of the pump, due to the inlet and outlet check valves (37;34).",
