The maximum deflection of the disk is defined by the angled plates. The stiffness of the disk increases monotonically with the deflection of the disk resulting in smooth clutch application.Type: GrantFiled: April 3, 2003Date of Patent: December 21, 2004Assignee: General Motors CorporationInventors: Chi-Kuan Kao, Anthony L. Smith, Andrew Leslie Bartos, Patrick Benedict Usoro

Publication number: 20040069589Abstract: A diaphragm spring for a friction clutch includes a ring-like body area and a plurality of spring tongues arranged at the inner edge in a row in a circumferential direction and extending radially inward from the body area. Openings are formed between adjacent spring tongues, each opening having a radially outer base area, at least one of the openings being limited in the circumferential direction by a wall area having a curvature which increases as the wall proceeds from the base area.Type: ApplicationFiled: August 11, 2003Publication date: April 15, 2004Applicant: ZF Sachs AGInventors: Martin Pahrisch, Ronald Beck, Alfred Schraut, Erwin Ziegler, Frank Hirschmann

Patent number: 6491189Abstract: A dispensing valve is disclosed which requires only a minimal force exerted on the valve actuator to maintain the valve in an open position. A resilient valve actuator having the characteristics of a nonlinear spring is provided at an actuator end of the valve body and operatively connected to a plunger, with the opposite end of the plunger mounting a resilient valve seal which serves to open and close a plurality of port openings. The valve is configured so as to allow it to be sterilized through high levels of radiation and through high temperature steam and chemical sterilization processes without degrading the valve structure or operation.Type: GrantFiled: April 6, 2001Date of Patent: December 10, 2002Assignee: International Dispensing CorporationInventor: Mitchell A. Friedman

Publication number: 20020089106Abstract: An apparatus for positioning and cushioning the rotor shaft of a fan motor. The apparatus is mounted within a shaft tube of the motor, which also receives the rotor shaft. The apparatus generally comprises a central portion, a peripheral portion and a connecting portion. When the apparatus mounted within the shaft tube of the motor, the outer edge of the peripheral portion fits tightly against the inner wall of the shaft. The connecting portion connects the central portion to the peripheral portion, and includes a plurality of connecting pieces projecting radially outward from the central portion to the peripheral portion, thereby providing elastic effects to the apparatus for cushioning the rotor shaft, which is loaded on the central portion. In an alternate embodiment, the apparatus further comprises a plurality of hooks that are adapted to engage an annular groove on the rotor shaft, thereby locking the shaft in place within the shaft tube.Type: ApplicationFiled: January 30, 2002Publication date: July 11, 2002Applicant: Sunonwealth Electric Machine Industry Co., Ltd.Inventor: Alex Horng
