Apparatus for regulating pressure in the hydraulic brake system

An apparatus for regulating hydraulic brake pressure, comprising:

• a housing having a closed cylindrical interior portion and an open end, wherein the closed cylindrical interior portion is capable of receiving hydraulic fluid and includes a hydraulic fluid communication valve, the housing being connected via the hydraulic fluid communication valve to a brake master cylinder, the hydraulic fluid communication valve communicating pressure via the received hydraulic fluid between the closed cylindrical interior portion and the brake master cylinder;
• a piston having a head receivable within the cylindrical interior portion of the housing, an expansion portion, and a rod extension extending opposite the head, the piston being slidable within the cylindrical interior portion of the housing in response to variations in the communicated hydraulic fluid pressure;
• a fixing member fixably attachable to the housing via the open end, the fixing member having an extension extending into the housing, wherein the fixing member extension has a concave portion for receiving the rod extension of the piston, wherein the fixing member extension concave portion has at least one wall, the at least one wall having at least one opening;
• wherein air is containable within the fixing member extension concave portion, wherein the sliding of the piston within the housing produces movement of an end of the rod extension of the piston, such that the distance between the end of the rod and the fixing member extension concave portion varies, and wherein air flows to and from the fixing member extension concave portion via the at least one opening in response to sliding of the piston in the housing;
• a spring extending between the expansion portion of the piston and the fixing member, the spring having a first end and a second end, the first end of the spring abutting the expansion portion of the piston, wherein the spring biasedly opposes movement of the piston toward the fixing member;
• and
• a pressure controller pad abuttably located between the second end of the spring and the fixing member, the pressure controller pad counteracting any imbalance between the second end of the spring and the fixing member;
• wherein the communicated hydraulic fluid pressure sliding the piston reduces brake lock and dampens abrupt changes in the communicated hydraulic fluid pressure.
