A side sprayer includes an inactive configuration, a normal active configuration, and a locked active configuration. The side sprayer includes three buttons to allow the user to transition between configurations of the side sprayer.

An electro-hydraulic actuation system for a sprayer comprises a hydraulic system, a hydraulic actuator, an electric actuator and a sprayer. The hydraulic system is for pressurizing a hydraulic fluid. The hydraulic actuator is powered by the hydraulic system. The electric actuator controls actuation of the hydraulic actuator by the hydraulic system. The sprayer is actuated by the hydraulic actuator.

A water stop switch device includes: a main body, a transmission element and a sealing element; the main body is disposed with a water passage, the sealing element is disposed in the water passage; one end of the sealing element is coupled to the transmission element in transmission way, the sealing element moves in the water passage to open the water passage; the other end of the sealing element and the main body surround to form a chamber; the side wall of the sealing element is disposed with a through hole connecting the water passage and the chamber; when the water passage is open, the chamber is full of water to reduce the pressure difference at two ends of the sealing element.

A shower device includes an elongated hollow waterway, a spray head configured to emit water, and a valve. The elongated hollow waterway extends in a longitudinal direction and has a first end configured to receive water, a second end, and an internal fluid passage extending from the first end to the second end. The second end has a port extending in a radial direction from the internal fluid passage through the waterway. The valve is configured to control a water flow rate from the internal fluid passage of the waterway to the spray head. The valve includes a valve body that surrounds the port and a control member operatively coupled to the valve body and surrounding at least a portion of the valve body. Rotation of the control member and valve body relative to the waterway provides a variable adjustment of the water flow rate to the spray head.

A telescopic nozzle device for cleaning a vehicle surface comprises a housing having a fluid inlet channel and a rod opening that opens towards the inside of the housing at one end of the rod opening and opens towards the outside of the housing at a second end of the rod opening. The device further comprises a hollow nozzle rod having a rod channel, an inlet opening, and a nozzle for ejecting washing fluid from inside the rod channel to the outside of the nozzle rod. The nozzle rod is moveable between a retracted position and an extended position. The device also includes a guiding system that guides the nozzle rod between the retracted and extended positions.

Provided is an application method including: a feeding step including feeding a viscous material to a discharge member; a temperature measurement step including measuring a temperature of the viscous material in a flow path through which the viscous material is fed to the discharge member; a pressurizing step including pressurizing the viscous material fed to the discharge member, based on the temperature measured in the temperature measurement step; and a discharge step including discharging, through the discharge member, the viscous material pressurized in the pressurizing step.

A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

The invention provides a method of packaging a sterilized product. The method includes the steps of providing a product and sterilizing the product. The sterilized product is enclosed in a first layer, which is substantially hermetically sealed to form a first sealed enclosure. The first sealed enclosure is enclosed in a second layer, which is substantially hermetically sealed to form a second sealed enclosure. The second sealed enclosure is enclosed in a third layer, which is substantially hermetically sealed to form a third sealed enclosure. The third sealed enclosure is enclosed in a fourth layer, which is substantially hermetically sealed to form a packaged product.

A mix manifold (16) includes a plurality of valves to control the flow of material therethrough. First and second valves (36a, 36b) are linked for simultaneous actuation. The first and second valves each include valve members (56a, 56b) disposed within and rotatable relative to seal bodies (58a, 58b). The valve members seal against the seal bodies and the seal bodies seal against the manifold. A solvent valve (36c) also includes a valve member (56c) in a seal body (58c). The first and second valves are configured to open only when the solvent valve is closed. The solvent valve is configured to open only when the first and second valves are closed. The solvent valve can rotate between a plurality of positions to control the flow of solvent to flowpaths downstream of the first and second valves.

A dosing dispenser system and a dosing dispenser include a rotatable control configured to allow a user to select a desired mixing ratio for a product contained in a container attached to the dosing dispenser with a transport medium, such as water, flowing through the dosing dispenser.
