Abstract
A drive system includes: a remote drive configured for being driven by an electrical motor; and an actuator spaced apart from and fluidically coupled with the remote drive and configured for being fluidically powered by the remote drive.
Claims12
A drive system, comprising:
- a remote drive configured for being driven by an electrical motor, wherein the remote drive includes a cable and pulley system and a plurality of piston assemblies coupled therewith, the plurality of piston assemblies each including an inner piston and an outer piston which are configured for sliding relative to one another and thereby for selectively opening and closing a working medium passage therebetween;
- and
- an actuator spaced apart from and fluidically coupled with the remote drive and configured for being fluidically powered by the remote drive.
A drive system, comprising:
- a remote drive configured for being driven by an electrical motor;
- and
- an actuator spaced apart from and fluidically coupled with the remote drive and configured for being fluidically powered by the remote drive, wherein the actuator includes a piston assembly, a plurality of cables, and a drive shaft coupled with one another, the piston assembly and the plurality of cables together being configured for causing the drive shaft to rotate.
A drive of a drive system, the drive comprising:
- the drive, which is a remote drive that is configured for being driven by an electrical motor, is configured for being spaced apart and fluidically coupled with an actuator of the drive system, and is configured for fluidically powering the actuator, wherein the remote drive includes a cable and pulley system and a plurality of piston assemblies coupled therewith, the plurality of piston assemblies each including an inner piston and an outer piston which are configured for sliding relative to one another and thereby for selectively opening and closing a working medium passage therebetween.
A drive of a drive system, the drive comprising:
- the drive, which is a remote drive that is configured for being driven by an electrical motor, is configured for being spaced apart and fluidically coupled with an actuator of the drive system, and is configured for fluidically powering the actuator, wherein the remote drive is configured such that the actuator includes a piston assembly, a plurality of cables, and a drive shaft coupled with one another, such that the piston assembly and the plurality of cables together are configured for causing the drive shaft to rotate.
A method of using a drive system, the method comprising the steps of:
- providing that the drive system includes a remote drive and an actuator, the remote drive being configured for being driven by an electrical motor, the actuator being spaced apart from and fluidically coupled with the remote drive, wherein the remote drive includes a cable and pulley system and a plurality of piston assemblies coupled therewith, the plurality of piston assemblies each including an inner piston and an outer piston which are configured for sliding relative to one another and thereby for selectively opening and closing a working medium passage therebetween;
- and
- fluidically powering the actuator by the remote drive.
