Abstract (en)

[origin: EP0070617A2] A scroll type fluid displacement apparatus is disclosed which includes a housing (10) having in inlet port (124) and an outlet port (123) connected with the interior (14) thereof, a fixed wrap (122) extending into the interior of the housing (10) from an end plate portion (121) of the housing (10), an orbiting scroll (122) orbitally disposed within the interior (14) with its wrap (222) and the fixed wrap (122) interfitting to form shifting sealed-off fluid pockets. In order to selectively connect between the lower pressure space (141) within the interior (14) and the center space (125) of both wraps, an opening portion (31) is formed through the end plate portion (121) of the housing (10), and a control means (32) is disposed in the opening portion (31) for controlling opening and closing the opening portion (31). Therefore, fluid displacement of the apparatus is controlled by the control means (32).
