  • Variable suction device for an A/C compressor to improve nvh by varying the suction inlet flow area
    Patent number: 9488289
    Abstract: A variable displacement compressor for an air conditioning system includes a suction throttle valve. The suction throttle valve includes a housing with a cavity formed therein. A first piston reciprocatingly disposed in the cavity is configured to cause a variable restriction of a flow of refrigerant through a suction inlet formed in the housing. The suction inlet provides fluid communication between a suction port and the cavity formed in the housing. The refrigerant flows through the suction port in a direction that is not parallel to a direction the piston reciprocates within the cavity. The suction throttle valve is configured to increase the restriction in the suction inlet when a crankcase pressure associated with the variable displacement compression is increased relative to an external suction pressure of the refrigerant entering the suction throttle valve.

  • Electrically operated valve actuator with electro-mechanical end stop detection device
    Patent number: 9482359
    Abstract: An electrically operated valve actuator effective for shifting a valve (10) between open and closed positions is disclosed, the valve actuator comprising a movable member in the form of a valve stem (21) connected to a valve body (14), the movable member being driven by an electric motor (22) in linear motion between valve closing and valve opening positions, wherein electrical power to the motor is supplied via a current (25) control including a supplied current detection device. The movable member is designed for an idling length of travel (L) in the opening and closing directions during which the valve (10) is either fully open or fully closed, and the movable member is associated with buffer means (30) that during the idling length of travel gradually increases the torque and power required to move the movable member further in the open and closed positions of the valve (10), respectively.

  • Cassette with infusion set containing spring-biased anti-freeflow mechanism for peristaltic infusion pump
    Patent number: 9468716
    Abstract: Flow control devices.—In a general embodiment, the present disclosure provides a cassette (30) comprising a housing having a flow restrictor (34), and a tube (36) attached to the housing and positioned adjacent the flow restrictor. The flow restrictor may be so constructed and arranged to rotate from a first position in which the flow restrictor prevents fluid flow through the tube to a second position in which fluid is able to flow through the tube when the cassette is positioned inside a pumping device. As a result, the cassette is designed to prevent free flow of fluid when an enteral feeding tube set is not installed in a pumping device.
