Abstract: Example embodiments disclose a valve seat that encloses a fluid passage for passage of a fluid from a fluid chamber, and a holding element that exerts a holding force on a valve body, the holding force acting in a direction towards a valve seat. In the event that the fluid acts on an effective surface of the valve body with a force or a pressure above a limit value, the valve body moves away from the valve seat. In the event that the fluid acts on an effective surface of the holding element with a force or a pressure above a limit value, the holding force acting on the valve body decreases. In doing so, the fluid acts on the holding element more strongly and/or earlier than on the valve body.

Abstract: A valve block includes a fluid-transfer plate with multiple inlet bores connecting to a common inlet channel, and multiple outlet bores connecting to a common outlet channel. The inlet bores and the outlet bores are arranged in a curved shape. The valve block also includes a pressure plate and diaphragm aligned and connected to the fluid-transfer plate in a way that allows pressurized material in the pressure plate to control the state of the channels formed by the inlet and outlet bores.

Abstract: A machine for making liquid or semi-liquid food products with a plurality of deformable feeding containers, each feeding container connected to a processing chamber for processing the base mixture and including a stirrer and a thermal treatment device for the base mixture, operating in conjunction with one another to convert the base mixture into a liquid or semi-liquid product. The operative connection of each feeding container to the processing chamber to transfer the base mixture from the feeding container to the processing chamber is made by a network of withdrawing ducts through an interposed pneumatically actuated valve which can be activated and deactivated independently of the remaining valves and which includes a valve body with an inlet duct and an outlet duct, and with a shutter acting to selectively interrupt or allow the connection between the inlet duct and the outlet duct.

Abstract: This invention discloses a valve including a body, an upper membrane, a lower membrane and a positioning block. The body has an upper channel, a lower channel, an accommodation space and a valve groove. The accommodation space defines an upper opening and a lower opening for respectively communicating with the upper channel and the lower channel. The valve groove is near the intersection of the lower channel and the accommodation space respectively communicating therewith. The upper and the lower membrane block the upper opening of the accommodation space and the lower opening. The positioning block is disposed between the upper membrane and the lower membrane and is able to push the lower membrane into the valve groove and abut against a sidewall of the valve groove. The valve is able to block the flow of water in the valve when the water flow is needed to be cut off.

Abstract: A valve includes a lower valve housing, a diaphragm, and an upper valve housing. A top surface of a piezoelectric pump is bonded to a bottom surface of the lower valve housing. A circular hole portion is provided in a central portion of a region of the diaphragm that opposes a projecting portion of the lower valve housing. The diaphragm is bonded to the upper valve housing and the lower valve housing, and a divided interior of a valve housing configures a first lower valve chamber, a second lower valve chamber, a first upper valve chamber, and a second upper valve chamber. A groove is located in a wall portion of the upper valve housing that opposes the diaphragm in the first upper valve chamber.
