A valve device increases or decreases a flow rate of EGR gas. The valve device includes a housing, a bypass valve body, an EGR valve body. The housing includes a first upstream passage into which the EGR gas cooled by an EGR cooler flows, a second upstream passage into which the EGR gas that bypasses the EGR cooler flows, a junction connected to each of a gas-flow downstream side of the first upstream passage and a gas-flow downstream side of the second upstream passage, and a downstream passage connected to the first upstream passage and the second upstream passage via the junction. The bypass valve body opens and closes the second upstream passage. The EGR valve body is provided in the downstream passage, rotates around an EGR valve axis.

A vessel pressure regulating system with a multidirectional control valve device includes: a pressure source; the multidirectional control valve device, which includes a housing, an actuation unit, and a working element, the housing having an interior space, an input port, and an output port, the input port being in communication with the pressure source, the actuation unit having a stationary portion and a driving portion, and the working element being controlled by the driving portion in order to open or close the output port; a vessel in communication with the output port; and a control unit for controlling the operation of the pressure source and of the driving portion. The vessel pressure regulating system enables a safety airbag of a vehicle or a similar device in a chair, bed, or the like to function effectively.

A simulator valve includes a housing having a pedal simulator passage and a master cylinder passage extending therethrough. The master cylinder passage is located longitudinally between the first housing surface and the pedal simulator passage. An armature is located at least partially within the housing for selective longitudinally reciprocating motion with respect thereto between first and second armature positions. A poppet is located within the housing for selective longitudinally reciprocating motion with respect thereto between first and second poppet positions. The poppet defines a first valve and a second valve the poppet includes a poppet bore extending longitudinally therethrough and selectively occluded by the first valve. A damped flow fluid path selectively permits fluid communication therethrough from the master cylinder passage to the pedal simulator passage. A free flow fluid path selectively permits fluid communication therethrough from the pedal simulator passage to the master cylinder passage.

A switching valve includes a valve body, a diaphragm, and a driving assembly. The valve body includes a valve cavity, a water inlet, a first water outlet, and a second water outlet in communication with the valve cavity. The diaphragm includes two unsealing parts connected with the driving assembly and respectively arranged opposite to the first water outlet and the second water outlet. Each unsealing part can control opening or closing of the first water outlet or the second water outlet. The driving assembly can individually drive each of the unsealing parts to switch between opening and closing such that at least one of the first water outlet and the second water outlet is in an open state.
