Abstract
An actuator including a housing, a piezo electric disc having a first side and a second side and defining an outer rim, an elastomeric seal, wherein the outer rim is received in the housing and the elastomeric seal engages the first side proximate the outer rim to seal the first side to the housing, the elastomeric seal engages the second side proximate the outer rim to seal the second side to the housing.
Claims27
An actuator comprising:
- a housing,
- a piezo electric disc having a first side and a second side and defining an outer rim,
- an elastomeric seal,
- wherein the outer rim is received in the housing and the elastomeric seal engages the first side proximate the outer rim to seal the first side to the housing, the elastomeric seal engages the second side proximate the outer rim to seal the second side to the housing.

An actuator comprising:
- a housing,
- a piezo electric disc having a first side and a second side defining an outer rim, an inner rim, and a disc plane,
- the piezo electric disc being mounted proximate the outer rim in the housing for movement of the inner rim relative to the outer rim during actuation,
- the actuator further including an actuator output defining a breather portion and an output element, the output element being fixedly connected to the breather portion at a coupling plane, the coupling plane being spaced apart from the disc plane,
- the breather portion being fixedly connected to the piezo electric disc proximate the inner rim at the disc plane,
- the breather portion having a plurality of holes to allow fluid to move from the first side to the second side and from the second side to the first side.

An actuator comprising:
- a housing,
- a piezo electric disc having a first side and a second side defining an outer rim, an inner rim, and a disc plane,
- the piezo electric disc being mounted proximate the outer rim in the housing for movement of the inner rim relative to the outer rim during actuation,
- a first connector having a first region engaging the piezo electric disc on the first side and a first portion for reacting against an output element, the first connector defining a first stiffness between the first region and the first portion,
- a second connector having a second region engaging the piezo electric disc on the second side and a second portion for reacting against the output element, the second connector defining a second stiffness between the second region and the second portion,
- the first portion being spaced from the second portion, and
- the first stiffness being different from the second stiffness, and
- an output element connecting the first connector to the second connector, the output element being adjustable to vary a clamping force between the first region and the second region, thereby adjusting a position of the output element relative to the disc plane.
