Abstract: A device for choking a fluid flow includes a pot-like base body, in the base of which a first passage opening is arranged, and a closing body guided axially moveably in the pot-like base body against a spring force of a spring element and having a second passage opening that forms a static choke point with a predefined fixed opening cross section. The closing body in combination with the spring element and the first passage opening forms a dynamic choke point with a dynamic opening cross section that is variably adjustable depending on a pressure difference.

Abstract: Disclosed is an inflation valve that enables a user to quickly inflate and deflate an inflatable object. The inflation valve can include an inflation chamber that is an adequate size to capture a breath of air blown by a user from a distance away from an outside opening of the inflation chamber. This allows surrounding air into the area of low pressure created by the moving air, thereby greatly increasing the amount of air entering the inflatable object. To prevent air from escaping the inflatable object, the inflation valve can include a non-invertible one-way valve and/or an invertible one-way valve. Each valve can prevent air from escaping the inflation chamber until adequate pressure is applied from the outside opening of the inflation chamber, for example, as a result of a user blowing air into the inflation chamber. The invertible one-way valve can be inverted to reverse the properties of the valve.

Abstract: A water-saving device structure is provided. When the pressure of an entry water is high, a water-barrier sheet body is pressed to cause a downwardly-moved elastic stopping portion to block a water-inflow opening of a water-outflow seat body, so that the water flow is conducted to a water-outflow opening through a water-conducting opening of the water-barrier sheet body. When the pressure of the entry water is low, the entry water is conducted to the water-outflow opening via one path traveling from the water-conducting opening of the water-bather sheet body to the water-outflow opening of the water-outflow seat body and the other path traveling along the clearances of stopping wall portions of the water-outflow seat body, a water-storage circular slot portion, the water-inflow openings of the water-outflow seat body and the water-outflow opening of the water-outflow seat body. Therefore, the outflow water with steady flow rate can be obtained.

Abstract: A compressor has a suction throttle valve, which includes a suction passage, a suction port, a valve body, an urging member, a valve chamber, a first communication hole, a closing valve and a valve seat. The closing valve closes the hole of the valve body by pressure difference between the valve chamber and the suction port. The valve seat limits movement of the closing valve toward the suction port. The hole of the valve body is closed when the closing valve is in contact with the valve body, and open when the closing valve is in contact with the valve seat. A communication passage is formed in the closing valve or the valve seat, which enables communication between the hole of the valve body and the suction port when the closing valve is in contact with the valve seat.

Abstract: The invention relates to a fuel overflow valve for a fuel injection system, particularly for limiting the pressure in a low-pressure region of the fuel injection system. The fuel overflow valve has a valve housing, in which a valve member is disposed in a stroke-moving manner, the stroke movement of the valve member controlling a connection of an inlet to the valve housing to a release region. The valve member is loaded by a valve spring in the direction of a locking position in which the connection of the inlet to the release region is interrupted, and is loaded by the pressure present in the inlet in the opening direction. The valve member may carry out a further stroke in the locking direction beyond the locking position thereof, where the valve spring does not act upon the valve member. Due to the increased stroke of the valve member, an improved balance of pressure and volume fluctuations is enabled in the low pressure region and the stroke of the valve spring, and thus the stress thereof, may be kept low.

Abstract: A fuel pump includes a pump housing having a compression chamber. A plunger is axially movable in the pump housing for pressurizing fuel in the compression chamber. A discharge valve is configured to open to supply fuel from the compression chamber to an internal combustion engine when pressure in the compression chamber is more than predetermined pressure. A fuel passage is configured to communicate a downstream of the discharge valve with an upstream of the discharge valve. An in-passage member is accommodated in the fuel passage. The in-passage member includes multiple members, which are combined to define a throttle portion for restricting fuel, which returns from the downstream of the discharge valve to the upstream of the discharge valve.
