Title:
SEMI-PLUGGED STAR GEROTOR AND METHOD OF ASSEMBLING THE SAME
Document Type and Number:
WIPO Patent Application WO/2012/093274
Kind Code:
A3
Abstract:
A gerotor assembly (13) includes a star (14), a ring (12), and an annular plug (18), as well as an o-ring (16). The star (14) defines a center opening (20) of a first diameter which is connectable to a low-pressure fluid reservoir (40). The ring (12) circumscribes the star (14). The ring (12) defines, in conjunction with a stationary end cap (24) of a fluid control device (1 1), a fluid channel (82) connectable to a high-pressure fluid supply (30). The plug (18) is circumscribed by the star (14), and defines a center bore (27) of a second diameter less than the first diameter. The o-ring(16) is positioned between the star (14) and the plug (18). The plug (18) forms a fluid seal against the end cap (24). A fluid control device (11) includes the above gerotor assembly (13) and a valve housing section (70). A method of assembling the gerotor assembly (13) and fluid control device (11) are also disclosed.
