Suction mechanism of a fluid displacement apparatus
 A fluid displacement apparatus includes a housing having a fluid inlet and fluid outlet. A suction chamber is formed between the first end of the displacement mechanism and the housing and communicates with the fluid inlet port. A discharge chamber is formed between the second end of the displacement mechanism and the housing and communicates with a hollow space. The hollow space is created between the inner block and the housing and communicates with the outlet port. Sealing devices are disposed between the suction chamber and the fluid inlet port for sealing the mating surfaces between the suction chamber and the fluid inlet port. The suction mechanism of the fluid displacement apparatus is thus easily assembled.
