  • Patent number: 10844755
    Abstract: A control valve for use in a cam timing phaser arrangement is disclosed comprising a cylindrical valve body, a rotational shuttle element coaxially located within a recess of the valve body, and a blocking pin. When using in a cam timing phaser arrangement having a first phasing chamber and a second phasing chamber, the control valve when non-actuated acts as a double check valve, preventing flow between chambers. Actuation of the blocking pin limits rotation of the rotational shuttle element and results in the control valve allowing flow in a single flow direction between phasing chambers. The allowed direction of flow can be controlled by controlling the timing of the deployment of the blocking pin. A cam timing phaser arrangement, internal combustion engine, and vehicle comprising such a control valve are also disclosed.

  • Patent number: 10844856
    Abstract: A scroll compressor includes a compression mechanism having fixed and movable scrolls forming a compression chamber, a motor to drive the movable scroll, a casing accommodating the compression mechanism and the motor, a housing accommodated inside the casing, a floating member supported by the housing, a first seal member, and first and second flow passages. An inside of the casing is partitioned into first and second spaces. The floater member can be pushed toward the movable scroll by pressure in a back-pressure space formed between the floating member and the housing. The first seal partitions the back-pressure space into first and second chambers. The first flow passage guides the refrigerant in the middle of compression in the compression mechanism to the first chamber. The second guides the refrigerant discharged from the compression mechanism to the second chamber.
