    摘要： A fluid management system includes a housing with a first port, a second port, and a third port, and a valve body moveable within the housing between a first position and a second position. The valve body is configured to seal the third port and permit fluid flow between the first and second ports in the first position, and to seal the first port and permit fluid flow between the second and third ports in the second position. The system further includes an actuator coupled to the valve body. The actuator includes a shape memory alloy material. A biasing element is coupled to the valve body to bias the valve body toward one of the first or second positions. The actuator is configured to move the valve body to one of the first or second positions against a biasing force of the biasing element in response to heating the actuator.

    摘要： A head-mounted display device includes a body, a fan, a first valve, and a first shape memory alloy element. The body is configured to be worn on a face of a user. The body has an air channel, an air outlet, and a first air inlet. The first air inlet is communicated with the air outlet through the air channel. The fan is disposed in the air channel and is configured to drive air inside the air channel to flow. The first valve is disposed in the air channel. The first shape memory alloy element is connected between the first valve and the body, and is configured to move the first valve to adjust airflow inside the air channel.

    摘要： A valve assembly includes a valve body, a valve bonnet, coupled to the valve body, an opening extending through the valve body and the valve bonnet, along a longitudinal axis, and a valve stem. The valve assembly also includes a valve member positioned at an end of the valve stem and arranged within the opening, the valve member being movable, along the longitudinal axis, between an open position and a closed position, an actuator housing coupled to the bonnet, and an adapter assembly coupled to the actuator housing. The adapter assembly includes an adapter element, the adapter element coupled to the valve stem and a force converter coupled to the adapter element, the force converter translating an external rotating force into an axial force.

    摘要： A pump includes a vibrating plate, a flow path forming member, a pump chamber, and a film valve. The vibrating plate is provided with a piezoelectric element, vibrates due to distortion of the piezoelectric element, and has a gap on an outer periphery. The flow path forming member is disposed so as to face the vibrating plate, and has a hole in a portion facing the vibrating plate. The pump chamber is surrounded by the vibrating plate and the flow path forming member, and has a central space communicating with the hole and an outer edge space communicating with the gap. The film valve is disposed in the pump chamber. The film valve is in contact with the vibrating plate and the flow path forming member when a pressure in the central space is lower than a pressure in the outer edge space.
