A mechanism (100) for storing and releasing mechanical energy, which stores a low-power energy continuously inputted by a power transmission mechanism into an energy storage mechanism, and then controllably drives output in a high-power manner. The mechanism comprises a bracket (10), a supporting main shaft (11) arranged on the bracket (10), a driving gear (101) which sleeves over and rotates about the supporting main shaft (11), wherein arranged on one side of the driving gear (101) is at least one set of energy storage and release device (102). The mechanism (100) for storing and releasing mechanical energy is structurally simple and reliable. A light-weight high-efficiency drive mechanism may be fabricated by using a light-weight structural material or a composite material, which may store a large amount of low-power energy which is inputted continuously. The stored energy may then be released in a high-power manner by means of manual operations or smart electronic control, in order to drive equipment which require higher power to drive, or to be fed back to an original driving device by means of a designated transmission mechanism to be used as auxiliary kinetic energy. The mechanism features high operation efficiency and low energy consumption, and is thus high efficient in storing and releasing energy.

A device for generating electricity includes a rotatable flywheel assembly including a flywheel and an axle rotatable about a first axis to spin the flywheel, support means to suspend the rotatable assembly and to allow the flywheel assembly to rotate with respect to the support means about a second axis to perform rotary motion normal to the first axis, and track means contactable with a free end of the axle for augmenting the spinning of the flywheel while it is also in rotary motion about the first and second axes. The rotating assembly is initially rotated to induce spinning motion of the flywheel and the axle until the flywheel has a predetermined rotational energy, the flywheel assembly being engaged with an electrical generator for converting the spinning motion of the flywheel assembly into electricity. The track means provides augmenting rotation to the flywheel assembly in at least an intermittent manner.

A gas ejection apparatus includes: a cylinder having a rotating member that rotates within the cylinder; a motor coupled to the rotating member of the cylinder and that causes gas to be compressed inside the cylinder and to he ejected from the cylinder by causing rotation of the rotating member; a control circuit board that controls the motor; and a case in which the cylinder, the motor and the control circuit board are disposed. The case extends in a planar direction and has side surfaces that are orthogonal to the planar direction. The motor and the cylinder are arranged adjacent to each other in the planar direction of the case. The control circuit board is disposed adjacent to and substantially parallel to one of the side surfaces of the case.

Aspects of the disclosure provide an electric actuator including a fail-safe mode of operation. The electric actuator includes a mechanical stop coupled to the output through the transmission, and a brake coupled to the second driving source through the transmission, the brake being engaged to establish the first pathway through the transmission between the first driving source and the output, the brake being disengaged to establish the second pathway through the transmission between the second driving source and the output, and the mechanical stop being engaged to restrict the output from rotating beyond the fail-safe position and the brake being disengaged to establish the third pathway through the transmission between the first driving source and the second driving source.

An electrical actuator with hammering mechanism includes a driving device, a transmission assembly driven by the driving device, an arc slot formed in the transmission assembly, a hammer element arranged in the arc slot, and a power valve arranged at one side of the hammer element. The driving device, when in operation, drives the transmission assembly to rotate and the arc slot is set in rotation in unison with the transmission assembly, while the hammer element is held at one side of the power valve so that a relative movement is generated between the arc slot and the hammer element. Thus, at the beginning of rotation of the transmission assembly, before the arc slot gets into impact with the hammer element, no loading that results in resistance is present so that full speed rotation can be conducted to thereby increase the kinetic energy before activation of the power valve.

A mechanism is introduced that allows transfer of mechanical rotational-energy generated in a liquid environment to a gas environment but does not allow the liquid to penetrate into the gas environment.
