A case for an electronic cigarette vaporiser, the case including an automatic lifting mechanism that lifts the vaporiser up a few mm from the case to enable a user to easily grasp the vaporiser and withdraw it from the case. The lifting mechanism can be spring-based. The case both re-fills the vaporiser with liquid and also re-charges a battery in the vaporiser.

A drain valve for a sterile container includes: a valve housing; a bypass that connects a container gas volume with an external gas volume; a valve body that blocks the bypass; and an actuator that displaces the valve body between a passage position and a blocking position. The valve body is displaceable according to a temperature and/or a pressure of the bypass gas volume. The valve housing has: at least one holding web, at least part of which can be located in a holding bracket of the valve receptacle; and a closure. The valve housing is pivotable from an open position into an installation position in which the closure can be fixed to a closure receptacle. When the valve housing is transferred into the installation position, the valve body is transferred into the blocking position and subjected to a closure force.

An embodiment includes a valve comprising: a valve channel that couples a valve input to a valve output; a one-way valve included within the channel; a filter; a first pressure relief port, wherein the first pressure relief port is configured to relieve negative pressure when pressure at the valve output is less than pressure at the valve input; a second pressure relief port, wherein the second pressure relief port is configured to relieve positive pressure when pressure at the valve output is greater than pressure at the valve input; wherein the one-way valve includes a monolithic portion that simultaneously seals the channel, the first pressure relief port, and the second pressure relief port; wherein the filter covers the first pressure relief port.

The present invention relates to a variable-flow-path air valve for water hammer prevention and a design method. The variable-flow-path air valve includes a valve body with a top provided with an air intake-exhaust port. A ball valve seat and a floating ball are arranged below the air intake-exhaust port. The valve body is provided with at least one swing check valve configured to be opened inward. The swing check valve includes: a swing valve disc connected to a valve body hinge, a variable-flow-path air inlet controlled by the swing valve disc to open and close, a device for limiting the opening degree of the swing valve disc, and a sealing device. In the present invention, the air valve takes in air through the air intake-exhaust port and the variable flow path, and discharges air only through the air intake-exhaust port.

An air supply device comprises an enclosure, a pump and a flow path switching unit. The flow path switching unit includes a pedestal part, a rotating part having an enclosure interior space communication portion and a groove portion, and a drive unit. The enclosure includes an air supply port, an air discharge port, and at least one object connection port. The pedestal part includes at least one first hole that is communicated to the at least one object connection port, and a second hole that is communicated to the air discharge port. The enclosure interior space communication portion is communicated to the air supply port through an interior space of the enclosure. The groove portion is separated from the enclosure interior space communication portion.

A breather drain includes a main body member having first, second and third portions. The first portion includes a threaded outer surface and a hollow inner cavity with first and second open opposite ends and at least one of the first and second open opposite ends extending from the hollow inner cavity to the threaded outer surface. The second portion includes a flange and having a central passageway therein. The second portion connects with the hollow inner cavity. The third portion includes a protrusion having first and second sides and extending from the second portion. The third portion also includes a transverse hole extending from the first side to the second side and connects with the central passageway.

A fuel vapor switching and venting valve for an internal combustion engine. The fuel vapor switching and venting valve includes an electromagnet with an armature, a first connection, a second connection, a first valve seat which is arranged between the first connection and the second connection, a spring, a flow limiting element, a second valve seat which is arranged on the flow limiting element, and a valve body coupled to the armature of the electromagnet. The valve body has a first contact surface with which the valve body can be lowered onto and lifted off of the first valve seat, and a second contact surface with which the valve body can be moved against the second valve seat. The second valve seat is axially displaceable. The spring loads the second valve seat in a direction of the valve body.
