ABSTRACT:
A fluid displacement apparatus includes a housing having a fluid inlet and a fluid outlet. A suction chamber is formed between one end of the displacement mechanism and the housing and communicates with the fluid inlet port. A discharge chamber is formed between other end of the displacement mechanism and the housing and communicates with the fluid outlet port. A first hollow space is created between a peripheral surface of a driving mechanism and the inner block, and communicates with the suction chamber. A second hollow space is created between the inner block and the housing and communicates with the discharge chamber. A pressure differential regulating device is disposed between the first hollow space and the second hollow space. Accordingly, a sealing mechanism of a driving mechanism achieves superior durability while maintaining the lubrication of a bearing under various operating conditions of the apparatus.
