摘要： Provided are a discharge plenum integrated with a valve stopper and a linear compressor including the discharge plenum. The valve stopper includes a radial member that extends radially and an axial member that extends axially from a radial inner end of the radial member. The axial member may have a tubular shape. The axial member may define a slot flow path that extends axially. The radial member may include a peripheral hole that extends axially. The radial inner side of the radial member may define a central hole of the axial member. The slot flow path and the peripheral hole may minimize a pressure drop and energy loss of a high-pressure fluid flowing from a compression portion to a discharge portion.

摘要： A linear compressor includes a cylinder that defines a compressor space and that is configured to compress refrigerant in the compressor space, a piston located in the cylinder and configured to perform a reciprocating motion in an axial direction relative to the cylinder, a mover coupled to the piston and configured to transmit a driving force to the piston to cause the piston to perform the reciprocating motion, a stator that defines a cylinder space that receives the cylinder, in which the stator is configured to generate the driving force together with the mover, and a supporting unit that includes an overlap portion that covers at least a portion of the stator, that is coupled to the stator, and that contacts the stator.

摘要： A method for detecting head crashing in a linear compressor includes sampling a rolling average of a peak applied voltage and a desired peak current each time that a current controller adjusts the desired peak current. The method also includes calculating a linear regression for a predicted peak applied voltage as a function of the desired peak current, calculating the predicted peak voltage for the motor of the linear compressor with the linear regression and a current value for the desired peak current from the current controller, and establishing that a piston of the linear compressor is soft crashing when the predicted peak voltage is different than the current value for the rolling average of the peak applied voltage by more than a threshold value.

摘要： An implantable infusion device includes a reservoir for housing an infusion medium and a drive mechanism having an inlet chamber, a piston and a piston channel. The inlet chamber is in fluid communication with the reservoir. The piston channel is in fluid communication with the inlet chamber, and has a distal end and a proximal end, the proximal end being closer to the inlet channel than the distal end. The piston is axially moveable within the piston channel to drive infusion medium out of the distal end of the piston channel. The clearance between the piston and the channel is sufficiently small to prevent undissolved gas in the inlet chamber from passing through the clearance. The inlet chamber may be sufficiently large to allow undissolved gas to accumulate without adversely affecting the performance of the infusion device.

摘要： A discharge valve assembly includes an outer shell. An inner sleeve is positioned within the outer shell. A side wall of the inner sleeve is spaced from a side wall of the outer shell along a radial direction. A distal end of the side wall of the inner sleeve is spaced from an end wall of the outer shell by a gap along an axial direction. The inner sleeve divides an interior volume of the outer shell into a first muffler cavity and a second muffler cavity. A related compressor is also provided.

摘要： A reciprocating compressor includes a cylinder that defines an inner space, a piston that is located in the inner space of the cylinder and that defines a compression space configured to receive refrigerant, a discharge cover that is coupled to a side of the cylinder and that defines a discharge space configured to receive refrigerant discharged from the compression space, and a valve plate that is located at a side space defined at the side of the cylinder and that partitions the side space into the compression space and the discharge space. The valve plate defines a discharge hole through which the compression space and the discharge space communicate with each other, in which the discharge hole includes an inlet that faces the compression space and an outlet that faces the discharge space. The inlet and the outlet have different shapes.
