A compressor integral with a Stirling engine having a pressure space comprises a housing, a partition wall provided in the housing, a first pressure chamber defined in the housing at one side of the partition wall and connected with the pressure space of the Stirling engine, and a second pressure chamber defined in the housing at the other side of the partition wall and connected with the first pressure chamber via an orifice. A rod passes through the partition wall and has a first end and a second end located in the first pressure chamber and the second pressure chamber, respectively. A third pressure chamber is defined by a first plate which is connected to the first end of the rod and a first bellows located between the first plate and the partition wall. A fourth pressure chamber is defined by a first plate which is connected to the second end of the rod and a second bellows located between the second plate and the partition wall. First and second passages are formed in the partition plate, and an intake valve device is provided for establishing fluid communication between the first passage and either the fourth pressure chamber or the third pressure chamber whichever is under expansion. A discharge valve device is also provided for establishing fluid communication between the second passage and either the fourth pressure chamber or the third pressure chamber whichever is under compression.

Compressor integral with stirling engine

A sanitary device of the type associated with a toilet bowl and having an extendable and retractable spray arm is provided with a hot water supply tank having a heating element therein. The pressure of the cold water supply forces the heated water through the spray nozzle and a partition is provided within the tank between the cold water inlet and the hot water outlet to prevent cold from being inadvertently forced through the hot water outlet.
