An HVAC unit includes a housing, at least one flap, and an actuator corresponding to the flap. The housing includes a first portion and a second portion defining an enclosure 'E'. A flap is received inside the housing with a first end of the flap engaged with a first portion of the housing and a second end of the flap engaged with a second portion of the housing via an intermediate rod. The actuator is arranged outside the enclosing part 'E', is connected to the flaps through an intermediate rod and drives the flaps, the intermediate rod comprises a stop piece which radially extends from at least one part of the periphery of the intermediate rod, and the stop piece is arranged between the second part of the shell and the flaps to limit the axial movement of the intermediate rod.
一种HVAC单元,包括壳体、至少一个瓣片、以及与瓣片相对应的致动器。壳体包括用于限定围封部“E”的第一部分和第二部分。瓣片被接纳在壳体的内部,其中瓣片的第一末端与壳体的第一部分接合,并且瓣片的第二末端经由中间杆与壳体的第二部分接合。致动器设置在围封部‘E”的外部,经由中间杆连接到瓣片并驱动瓣片。中间杆包括从其周缘的至少一部分径向延伸的止挡件。止挡件设置在壳体的第二部分与瓣片之间以限制中间杆的轴向运动。
