  • Patent number: 10247183
    Abstract: A horizontal piston compressor is disclosed, including a frame with a cylinder, and a piston reciprocably received in the cylinder. The has piston h an inner chamber and first and second end walls. The piston and the cylinder form a compression chamber for compressing the gas. A valve and an orifice are disposed in the first end wall, and are configured to supply gas from the compression chamber to the inner chamber during a compression stroke of the piston. A gas bearing supports the piston relative to the frame. The gas bearing includes an opening for supplying gas from the inner chamber to a space between the piston and the cylinder such that the gas supplied to the space exerts an upward pressure on the piston. The valve may be a spring-loaded valve, and the orifice may be an orifice insert positioned between the valve and the compression chamber.

  • Patent number: 9989048
    Abstract: A method for controlling a stroke velocity in a pump includes using a sensor to detect a start of a pump stroke and an end of the pump stroke. A stroke time is calculated, the stroke time being a time period between the start of the pump stroke and the end of the pump stroke. The stroke velocity is calculated based on a stroke length and the stroke time. The stroke velocity is compared to a reference stroke velocity. A hydraulic supply pressure to the pump is increased if the calculated stroke velocity is less than the reference stroke velocity, and the hydraulic supply pressure is decreased if the calculated stroke velocity is more than the reference stroke velocity.
