A connector for transferring fluid and method therefor. The connector may have a first port and a second port which may be coupled together at a main channel with a valve element therein controlling fluid flow through the first port. The first port joins the main channel to provide a fluid path around the valve element and through the second port.

Methods and system are provided for a flap valve having a sealing element. In one example, a system include a front side of the flap valve having a first sealing element and a back side of the flap valve having a second sealing element, where the first sealing element and the second sealing element are located along a circumferential edge of the flap valve and spaced away from its geometric center.

An annular groove has: a side peripheral surface that is shaped in a ring form and is formed such that the side peripheral surface inwardly extends from a bottom surface of the annular groove in a radial direction of a tubular member and is joined to an inner peripheral wall of the tubular member; and a specific shape surface that is formed along at least a part of the side peripheral surface between a bottom surface side end part and an inner peripheral wall side end part of the side peripheral surface such that a diameter of the specific shape surface is progressively reduced in an axial direction of the tubular member from one axial side, at which the bottom surface is placed, toward another axial side, at which the inner peripheral wall is placed.

A connector for transferring fluid, the connector may have a first port, a second port, and a third port which may be fluidly coupled together at an internal chamber with a first valve element therein controlling fluid flow through the second port. The connector can have ribs extending along the connector to provide a fluid path around the valve element and between the first port and the second port. The valve element can separate the internal chamber into an air chamber and a liquid chamber, and the third port can be continuously coupled to the liquid chamber regardless of a position of the valve element.

A hydraulic module configured to control a hydraulic fluid flow of a connecting rod of an internal combustion with variable compression, the connecting rod including an eccentrical element adjustment arrangement for adjusting an effective connecting rod length, wherein the eccentrical element adjustment arrangement includes at least a first cylinder and a second cylinder configured as hydraulic chambers, wherein a first inlet for feeding hydraulic fluid into the first cylinder through a supply conduit and a second inlet for feeding hydraulic fluid into the second cylinder through the supply conduit and a first outlet for draining hydraulic fluid from the first cylinder and a second outlet for draining hydraulic fluid from the second cylinder are provided, wherein the hydraulic module includes at least one piston that is displaceable in a housing into a first switching position or a second switching position.

A check valve structure includes: a valve casing communicating with each of inflow and outflow paths for a fluid; and a valve element which is disposed in the valve casing and configured of an elastic material. The valve element has a thin portion, and a thick portion protruding from the substantial center of one surface of the thin portion. The valve casing has: a valve element support portion including an annular bottom portion capable of supporting an outer edge of a bottom portion of the thick portion, and a peripheral wall portion continuing to an outer peripheral edge of the annular bottom portion; and a valve seat portion including a valve element contact portion which is in contact with a vicinity of an outer peripheral edge portion on the other surface side of the thin portion, and a valve seat surface which can be in contact with the thin portion.

A compressor includes a compression mechanism configured to suck and compress a refrigerant from a suction space to discharge the refrigerant to a discharge space by a driving force transmitted thereto. The compressor includes an oil storage chamber provided in the discharge space to collect oil separated from the refrigerant discharged from the compression mechanism, an oil recovery passage configured to guide the oil in the oil storage chamber to the suction space, and a decompression mechanism provided in the oil recovery passage to reduce a pressure of the oil passing through the oil recovery passage by an orifice hole having an inner diameter smaller than the oil recovery passage. The decompression mechanism is configured such that, when a pressure in the oil storage chamber is increased, the inner diameter of the orifice hole is reduced.

A connector for transferring fluid and method therefor. The connector may have a first port and a second port which may be coupled together at a main channel with a valve element therein controlling fluid flow through the first port. The first port joins the main channel to provide a fluid path around the valve element and through the second port.

A gas-filled resilient body and uses thereof are described. The gas-filled resilient body may be used as a valve member, as a spring or as a gas-propelled dispenser.

A hydraulic module with a switch valve for controlling a flow of a hydraulic fluid in a connecting rod for an internal combustion engine with variable compression with an eccentric element adjustment arrangement for adjusting an effective connecting rod length, wherein the eccentrical element adjustment arrangement includes a first cylinder and a second cylinder configured as hydraulic chambers, wherein a first inlet is provided for feeding the hydraulic fluid into the first cylinder and a second inlet is provided for feeding the hydraulic fluid into the second cylinder, wherein a first outlet is provided for draining the hydraulic fluid from the first cylinder and a second outlet is provided for draining the hydraulic fluid from the second cylinder wherein a first check valve is associated with the first cylinder and a second check valve is associated with the second cylinder.
