Abstract: PURPOSE: A low pressure accumulator for a break system is provided to effectively prevent fluid pressure from being leaked through a space between a piston and the inner wall of a cylinder without an O-ring which was conventionally installed on the circumference of the piston. CONSTITUTION: A low pressure accumulator for a break system comprises a cylinder (10), a piston (20), an elastic member (30), and a lip seal part (21). One end of the cylinder includes a fluid pressure inlet (12) to connect an oil storage space (11) to a fluid pressure line and the other end of the cylinder is closed by a sealing cap (40). The piston is installed inside the cylinder to be able to move back and forth with the front end surface faces the flowing direction of fluid pressure to the oil storage space. The elastic member is installed between the sealing cap and the piston and elastically supports the piston towards the fluid pressure inlet. The lip seal part is integrated with the front end outer surface of the piston to seal a space between the piston and the inner wall of the cylinder.
