A compressor housing (1) is used in a compressor which uses a compressor impeller (5) provided in an intake air flow path more to a downstream side than a blow-by gas inlet. The compressor housing (1) includes an impeller chamber (2), and an intake air duct (6) which extends along an axis line (C). The duct (6) includes an inner-wall face (61). A step part (67) that is arc shaped along a circumferential direction of the impeller (5) and has a distance along the radial direction of the impeller (5) from the axis line (C) that is farther at a downstream side than at an upstream side thereof is formed in the inner-wall face (61) more to an upstream side along the axis line (C) than the intake air inlet (22).Type: ApplicationFiled: August 4, 2017Publication date: February 8, 2018Applicant: HONDA MOTOR CO., LTD.Inventors: Akihiko Fujiwara, Atsushi Shimizu, Shota Kadokura

Publication number: 20180038388Abstract: A compressor system including a motor including: a rotor that rotates around an axis and a stator disposed on an outer circumferential side of the rotor with a gap from the rotor; a compressor that rotates together with the rotor to generate a compressed fluid; and a partitioning member that is disposed in the gap formed between the rotor and the stator to partition the gap in the radial direction, and forms a rotor-side flow passage through which a cooling fluid can flow along the axis with the rotor, and a stator-side flow passage through which the cooling fluid can flow along the axis with the stator. The partitioning member has a cylindrical shape with the axis as a center and has a shape in which a thickness dimension in a radial direction of the rotor increases from one side to the other side of the axis.Type: ApplicationFiled: November 18, 2015Publication date: February 8, 2018Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventor: Satoshi Mizukami

Publication number: 20180038390Abstract: A pressure vessel having an adjustable volume to adjust a hydraulic time delay produced by the pressure vessel. The pressure vessel can include a piston with an adjustable stroke and a rod received in a housing to limit the stroke of the piston. The piston divides the housing into a pressure cavity and a reset cavity. Spacers can be removably coupled to the rod to limit the stroke of the piston. Optionally, a brake wall can be positioned to obstruct the path of the rod to limit the stroke of the piston.Type: ApplicationFiled: August 2, 2016Publication date: February 8, 2018Applicant: Cameron International CorporationInventor: Kody Carrillo

Publication number: 20180038392Abstract: An actuator assembly includes an actuation member, a release member, and a source of pressurized gas, wherein during a normal mode of operation, the actuation member and the release member are engaged to move in unison, and wherein during an emergency mode of operation, pressurized gas automatically decouples the actuation member from the release member to move separately. In accordance with yet other aspects of the present disclosure, an electro-mechanical actuator includes an electro-mechanical drive system and an integrated backup system operated by a gas generator, wherein when the backup system is activated, the electro-mechanical drive system is decoupled and the actuator moves to a predetermined position and mechanically locks in place.Type: ApplicationFiled: October 17, 2017Publication date: February 8, 2018Inventors: Christopher L. Fenn, Patrick Cronin

Publication number: 20180038393Abstract: A gas pressure actuator includes a launcher, a gas generator that is disposed at a first axial end of the launcher, a rocket part placed inside the launcher, an end pad and a sealing gasket respectively disposed at a second axial end of the launcher, and a gasket holder supporting the gasket. The rocket part includes a first portion disposed at a location corresponding to the first axial end and a second portion that has a diameter less than that of the first portion and that ranges from the first portion toward the second axial end. The end pad includes a position determination part that determines positioning of the rocket part and restricts the rocket part from being displaced in a direction away from the first axial end. The gasket holder may be pressed by the first portion when the rocket part protrudes from the launcher and plastically deformed.Type: ApplicationFiled: February 19, 2016Publication date: February 8, 2018Inventors: Koji INUZUKA, Kazuhiro ABE
