Patent number: 8887746Abstract: In various embodiments, an electronic flow selector of a fluid flow control system may be used to select a flow rate of a fluid. When the system is in an electronic mode, an encoder may electronically encode the fluid flow selection. A controller may receive the electronically encoded flow selection and transmit a corresponding control signal to an electronic valve to allow the fluid to flow at the selected flow rate. When the system is in a manual mode, backup manual flow selectors may be used to directly control the flow rate of a fluid. When the system is in a manual mode, the mechanical backup flow selectors may be in a deployed position. When the system is in an electronic mode, the mechanical backup flow selectors may be in a retracted position. Particular applications to gases and anesthesia delivery are disclosed herein.Type: GrantFiled: November 14, 2012Date of Patent: November 18, 2014Assignee: Mindray DS USA, Inc.Inventors: Peter B.

Patent number: 8864103Abstract: The invention concerns a valve actuator (1) comprising a housing (2) and a nut and screw arrangement. A first portion (5) of the nut and screw arrangement is operated by an electric motor (7), which is fixed to the housing (2). A means (8) is in contact with a second portion (6) of the nut and screw arrangement, and a resilient means (9) is acting between the means (8) and the housing (2). A relative rotation between the threaded nut (3) and the threaded screw (4) leads to a translation of the means (8) and an energizing or de-energizing of the resilient means (9). A locking means (10) locks the resilient means (9) in an energized state by locking the relative rotation of the nut and screw arrangement. When the locking means (10) are released, the resilient means (9), when de-energizing, acts on the means (8), leading to a translation of the means (8).Type: GrantFiled: September 23, 2008Date of Patent: October 21, 2014Assignee: Aktiebolaget SKFInventors: Torbjörn Lövgren, Pontus Louis Claesson
