Abstract: A braking apparatus includes a pedal configured to be pressed by a driver to cause braking, a master cylinder part in which pressure of oil is amplified by the pressure applied to the pedal part, a block part configured to be supplied with the oil from the master cylinder. An electric pump part is inserted into block part and is configured to amplify the pressure of the oil in the block part. A wheel cylinder part is connected to the block part that is configured to receive pressurized oil from the block part and to generate a braking force for a wheel. The block part defines a space into which the electric pump part is inserted and a plurality of oil movement paths that are connected to the space and separate from each other when the electric pump part is inserted into the space.

Abstract: According to at least one aspect, the present disclosure provides a piston pump comprising: a piston unit configured to reciprocate by driving of a motor cam; a sleeve unit disposed to surround at least a part of the piston unit and having a space in which brake oil is stored; and a check valve unit facing the sleeve unit and discharging the brake oil to an outside of the sleeve unit when a pressure of the brake oil increases, wherein the piston unit includes a first piston having a first end in contact with the motor cam and reciprocating, a second piston having a first end coupled to a second end of the first piston and configured to press the brake oil, and a spring cap coupled to a second end of the second piston and disposed to accommodate an inlet spring therein.
